Objective: Objective scientific knowledge for many authors more valuable than true subjective belief is determined by research on primary data but a renewed analysis of already recorded or published data is common too. Ever since, an appropriate experimental or study design is an important and often a seriously underappreciated aspect of the informativeness and the scientific value of any (medical) study. The significance of study design for the reliability of the conclusions drawn and the ability to generalize the results from the sample investigated for the whole population cannot be underestimated. In contrast to an inappropriate statistical evaluation of a medical study, it is difficult to correct errors in study design after the study has been completed. Various mathematical aspects of study design are discussed in this article.
Methods: In assessing the significance of a fair study design of a medical study, important measures of publication bias are introduced. Methods of data or publication bias analysis in different types of studies are illustrated through examples with fictive data. Formal mathematical requirements of a fair study design which can and should be fulfilled carefully with regard to the planning or evaluation of medical research are developed.
Results.
Various especially mathematical aspects of a fair study design are discussed in this article in detail. Depending on the particular question being asked, mathematical methods are developed which allow us to recognize data which are self-contradictory and to exclude these data from systematic literature reviews and meta-analyses. As a result, different individual studies can be summed up and evaluated with a higher degree of certainty.
Conclusions
This article is intended to give the reader guidance in evaluating the design of studies in medical research even ex post which should enable the reader to categorize medical studies better and to assess their scientific quality more accurately.

Bayesian models have become very popular over the
last years in several fields such as statistics, signal processing, and machine learning. Bayesian inference needs the approximation of complicated integrals involving the posterior distribution. For this purpose, Monte Carlo (MC) methods such as Markov Chain Monte Carlo (MCMC) and Importance Sampling (IS) algorithms, are often employed. In this work, we introduce a compressed MC (C-MC) scheme in order to compress the information obtained previously by MC sampling. The basic C-MC version is based on the stratification technique, well-known for variance reduction purposes. Deterministic C-MC schemes are also presented, which provide very good performance. The compression problem is strictly related to moment matching approach applied in different filtering methods, often known as Gaussian quadrature rules or sigma-point methods. The connections to herding algorithms and
quasi-Monte Carlo perspective are also discussed. C-MC is particularly useful in a distributed Bayesian inference framework,
when cheap and fast communications with a central processor are required. Numerical results confirm the benefit of the introduced schemes, outperforming the corresponding benchmark methods.

In this paper, asymptotic expansions of the distributions and densities of powered extremes for Maxwell samples are considered. The results show that the convergence speeds of normalized partial maxima relies on the powered index. Additionally, compared with previous result, the convergence rate of the distribution of powered extreme from Maxwell samples is faster than that of its extreme.

Background: Human papillomavirus (HPV) has an important role in the oncogenesis of several malignant diseases. Some observational studies demonstrated the presence of HPV even in human prostate cancer (PC) while other studies failed on this point. The relationship between HPV infection and PC remains unclear. The aim of the present meta-analysis study is to investigate whether HPV serves as a cause or as the cause of PC.
Methods: The PubMed database was searched for suitable articles. Previously published expert reviews and systematic meta-analysis were used as an additional source to identify appropriate articles. Articles selected for this meta-analysis should fulfill the following inclusion criteria: (a) no data access barrier, (b) polymerase chain reaction (PCR) DNA based identification of HPV. The method of the conditio sine qua non relationship was used to prove the hypotheses whether being married is a necessary condition (a conditio sine qua non) of PC. In other words, without being married no PC. The method of the conditio per quam relationship (sufficient condition) was used to prove the hypotheses if HPV is present in human prostate tissues then PC is present too. The mathematical formula of the causal relationship k was used to prove the hypothesis, whether there is a cause effect relationship between HPV and PC. Significance was indicated by a p-value (two sided) of less than 0.05.
Results: In toto more than 136 000 000 cases and controls were re-analysed while more than 33 studies were considered for a meta-analysis. Several studies support the hypotheses without being married no PC. All the studies considered for a re-analyses support the null-hypotheses if HPV then PC, while the cause effect relationship between HPV and PC was highly significant.
Conclusions: Human papillomavirus is the cause of human prostate cancer.

In this research, we present neutrosophic decision-making, which is an extension of the classical decision-making process by expanding the data to cover the non-specific cases ignored by the classical logic, which in fact support the decision-making problem. The lack of information besides its inaccuracy is an important constraint affecting The effectiveness of the decision-making process, and we will rely on the decision tree model, which is one of the most powerful mathematical methods used to analyze many decisionmaking problems, where we extend it according to the neutrosophic logic by adding some indeterminate data (in the absence of probability) or by substituting the classical probabilities with the neutrosophic probabilities (in case of probability). We call this extended model the neutrosophic decision tree, which results in its use to reach the best decision among the available alternatives because it is based on data that is more general and accurate than the classical model.

Probability distributions play a very important role in many applications. This paper describes a modeling approach for distributional time series. Probability density functions (PDFs) are approximated by real-valued vectors via successively applying the log-quantile-density (LQD) transformation and functional principal component analysis (FPCA); state-space models (SSMs) for real-valued time series are then applied to model the evolution of PCA scores, corresponding results are mapped back to the PDF space by the inverse LQD transformation.

In Situational Underlying Value (SUV) for Baseball, Football and Basketball: A Statistic to Measure Individual Performance in Team Sports, an all-encompassing, overall statistic to measure performance by individual players in the team sports of major league baseball, professional football (NFL), and NCAA men's college basketball was developed. This work supplements and extends the development and initial demonstrations of the use of the SUV statistic for these three team sports by tracking the performance of three specific teams in these three sports over a significant portion of their most recent seasons: (1) for major league baseball, 54 of the 162 games played by the Seattle Mariners in 2017; (2) for professional football, five of the 16 games played by the Seattle Seahawks in 2017; and (3) for NCAA Men's College Basketball, the five games played by the Loyola of Chicago Ramblers in the 2018 NCAA Division I Men's Basketball Tournament. The SUV statistics for the players who participated in these games are tracked and accumulated for comparison among themselves and, for those who participated in a significant portion of these games, further compared against the traditional statistics for each team over the entire season (or, in the case of the Loyola of Chicago Ramblers, the complete five games of the Basketball Tournament). The goal is to examine the efficacy of this one overarching statistic, the SUV, in representing player performance "in the clutch" vs. more subjective interpretation of the myriad of different "traditional" statistics currently used. Anomalies between the SUV and traditional statistics results are examined and explained, to the extent practicable given the scope of the SUV analysis (partial seasons). Whether or not this effort proves successful is left to the reader's conclusion based on t
he results and comparisons performed.

Objective: Atrial fibrillation (AF) is very frequent and clinically significant arrhythmia. The incidence of atrial fibrillation is continuously rising. Meanwhile several risk factors for AF development have been identified but the etiology is not cleared.
Methods: A systematic review and re-analysis of studies which investigated the relationship between AF and some risk factors was conducted. The method of the conditio sine qua non relationship, the method of the conditio per quam relationship, the method of the exclusion relationship and the mathematical formula of the causal relationship k were used to proof the hypothesis. Significance was indicated by a p-value of less than 0.05.
Results: The studies analysed were able to provide direct and indirect evidence that AF is caused by a process of inflammation while a direct identification of the factor causing AF was not possible. Still, it appears to be very probable that Epstein-Barr virus (EBV) is the cause of AF.
Conclusion: Atrial fibrillation (AF) is caused by an inflammatory process.
Keywords: Epstein-Barr virus, atrial fibrillation, causal relationship

**Comments:** 55 Pages. Third in the SUV series, addressing defensive SUV (and revised pitching SUV) for major league baseball, including "proof of principle."

In Situational Underlying Value for Baseball, Football and Basketball – A Statistic (SUV) to Measure Individual Performance in Team Sports, an all-encompassing, overall statistic to measure “clutch” performance by individual players in the team sports of major league baseball, professional football, and NCAA men’s college basketball was developed, called “Situational Underlying Value” (SUV). [1] Based on the concept of “run expectancy,” it assigns an SUV to each base as a function of the number of outs, including a negative value for making an out. There, and in “Proof of Principle” for Situational Underlying Value (SUV) – A Statistic to Measure Clutch Performance by Individuals in the Team Sports of Major League Baseball, [2] it was applied exclusively to hitters and pitchers. Its derivation is explained in Reference 1, with additional discussion provided in Reference 2.
Reference 1 provides two example games to show how the SUVs accrue for each team’s hitters and pitchers. The goal of this third work, which includes “Proof of Principle” as in Reference 2, is to track the performance of a team’s individual fielders defensively, including an enhancement to the approach for pitching previously developed in Reference 2, over the same substantial portion of an entire season. One-third of the 2017 season, i.e., 54 games, have again been selected for the Seattle Mariners, starting with Game 002 and tracking every third game up through Game 161. The SUVs are based on the play-by-play descriptions provided in “Baseball Reference,” https://www.baseball-reference.com/. [3] Summary SUV analyses for all 54 games are provided below, with a roll-up of cumulative SUVs every six games. Also, the actual play-by-plays are included for every third game analyzed, starting from Game 005 (i.e., for Games 005, 014, 023, 032, 041, 050, 059, 068, 077, 086, 095, 104, 113, 122, 131, 140, 149 and 158), providing a total for 18 games. For the rest (which are only summarized), the reader should consult Reference 3.
There is an important change to the above table for defensive tracking, also applied to the enhanced pitching analysis, namely the reversal of all the SUV signs. This enables “positive” defensive outcomes (outs) to be assigned positive SUVs, while “negative” outcomes (reaching base or advancing) are assigned negative SUVs. The assignment of defensive SUVs is somewhat more involved than that for hitting. Specific assignments, most frequently encountered, are presented below.

A piece-wise quadratic spline is introduced as a time series coming with unequal time steps, and where the second derivative of the spline at the junction points is impacted by random Brownian motion. A measurement error is also introduced, and this changes the spline into semi-parametric regression. This makes a total of two dispersion parameters to be estimated by a proposed REML analysis that unitizes the K-matrix. The spline itself only has three location effects that are treated as fixed, and must be estimated. A proposed prediction of a future observation beyond the spline’s end point is presented, coming with a prediction error variance.

Background: Epstein-Barr virus (EBV) has an important role in the oncogenesis of several malignant diseases. Reports demonstrated even the presence of Epstein-Barr virus in gastric carcinoma (GC). However, the pathogenic role of EBV in CG is uncertain. The present investigation was carried out to investigate a possible causal relationship between GC and EBV.
Statistical Analysis: The method of the conditio sine qua non relationship was used to proof the hypothesis whether gastric cancer is a necessary condition (a conditio sine qua non) of the presence of EBV in human gastric tissues. In other words, without GC no EBV positivity in human stomach. The mathematical formula of the causal relationship k was used to proof the hypothesis, whether there is a cause effect relationship between gastric cancer and EBV. Significance was indicated by a p-value (two sided) of less than 0.05.
Results: In toto 26 ISH based studies with a sample size of N = 11860 were re-analyzed. All the studies analyzed support the null-hypothesis without GC no EBV positivity in human gastric tissues. In other words, gastric cancer itself is a conditio sine qua on of EBV positivity in human gastric cancer while the cause effect relationship between gastric cancer and EBV was highly significant.
Conclusions: Epstein-Barr virus in neither a cause or the cause of human gastric cancer.

Background: Unfortunately, despite recent scientific advances the cause of malignant melanoma is not identified. The incidence of malignant melanoma increases and malignant melanoma continues to represent a significant individual and public health challenge.
Objectives: In this systematic review studies were re-analyzed so that some new inferences can be drawn.
Statistical Analysis: The method of the conditio per quam relationship was used to proof the hypothesis whether the presence of human papillomavirus guarantees the presence of malignant melanoma. In other words, if human papillomavirus is present, then malignant melanoma is present too. The mathematical formula of the causal relationship k was used to proof the hypothesis, whether there is a cause effect relationship between human papillomavirus and malignant melanoma. Significance was indicated by a p-value of less than 0.05.
Results: The studies analyzed support the null-hypothesis that the presence of human papillomavirus guarantees the presence of malignant melanoma. In other words, human papillomavirus is a conditio per quam of malignant melanoma while the cause effect relationship between human papillomavirus and malignant melanoma was highly significant.
Conclusions: Human papillomavirus is a sufficient condition of malignant melanoma. Human papillomavirus is a cause of malignant melanoma.

We present in this paper the neutrosophic randomized variables, which are a generalization of the classical random variables obtained from the application of the neutrosophic logic (a new nonclassical logic which was founded by the American philosopher and mathematical Florentin Smarandache, which he introduced as a generalization of fuzzy logic especially the intuitionistic fuzzy logic ) on classical random variables. The neutrosophic random variable is changed because of the randomization, the indeterminacy and the values it takes, which
represent the possible results and the possible indeterminacy.Then we classify the neutrosophic randomized variables into two types of discrete and continuous neutrosophic random variables and we define the expected value and variance of the neutrosophic random variable then offer some illustrative examples.

Objective: The present publication investigates the relationship between the presence of Human cytomegalovirus (HCMV) in renal tissue and IgA Nephropathy (IgAN).
Methods: A systematic review and re-analysis of studies which investigated the relationship between HCMV and IgAN was conducted aimed to answer the following question. Is there a cause-effect relationship between HCMV and IgAN? The method of the conditio sine qua non relationship was used to proof the hypothesis whether the presence of HCMV guarantees the presence of IgAN. In other words, without HCMV no IgAN. The mathematical formula of the causal relationship k was used to proof the hypotheses is, whether there is a cause-effect relationship between HCMV and IgAN. Significance was indicated by a p-value of less than 0.05.
Results: The studies analysed were able to provide strict evidence that HCMV is a necessary condition (a conditio sine qua non), a sufficient condition and a necessary and sufficient condition of IgAN. Furthermore, the cause-effect relationship between HCMV and IgAN (N=37, k =+0.514619883, p value (k) =0.001746216) was highly significant.
Conclusions: On the basis of published data and ongoing research, sufficient evidence is given to conclude that HCMV is the cause of IgA Nephropathy.

BACKGROUND: Several observational studies investigated the relationship between human papillomavirus (HPV) infection and the risk of prostate cancer (PC) and have suggested conflicting results about this relationship. However, the relationship between HPV infection and PC remains unclear. The aim of the present meta-analysis study is to investigate whether HPV serves as a cause of PC.
METHODS: The PubMed database was searched for suitable articles. Previously published expert review and systematic review were used as an additional source to identify appropriate articles. Articles selected for this meta-analysis should fulfil the following inclusion criteria: (a) no data access barrier (b) PCR DNA based identification of HPV.
RESULTS: The studies analysed were able provide evidence that without being married no (HPV infection of a men/prostate cancer).The X² value of the total 20 articles indicated a significant causal relationship between HPV and PC. In other words, if HPV infection of human prostate, then prostate cancer.
CONCLUSION: In conclusion, Human papillomavirus is the cause of prostate cancer.
KEYWORDS: Human papillomavirus, prostate cancer, causal relationship, causality

Successive real-valued measurements of any physical chaotic oscillator can serve as entropy inputs to a random number generator (RNG) with correspondingly many whole numbered outputs of arbitrarily small bias, assuming that no correlation exists between successive such measurements apart from what would be implied by their probability distribution function (AKA the oscillator’s analog “generator”, which is constant over time and thus asymptotically discoverable).
Given some historical measurements (a “snapshot”) of such an oscillator, we can then train the RNG to expect inputs distributed uniformally among the real intervals defined by those measurements and spanning the entire real line. Each interval thus implies an index in sorted order, starting with the leftmost which maps to zero; the RNG does nothing more than to perform this mapping. We can then replace that first oscillator with a second one presumed to abide by the same generator. It would then be possible to characterize the accuracy of that presumption by quantifying the ensuing change in quality of the RNG.
Randomness quality is most accurately expressed via dyspoissonism, which is a normalized equivalent of the log of the number of ways in which a particular distribution of frequencies (occurrence counts) of masks (whole numbers) can occur. Thus the difference in dyspoissonism between the RNG output sets will serve to estimate the information divergence between theirrespective generators, which in turn constitutes a ranking quantifier for the purpose of anomaly detection.

This paper deals with the application of Neutrosophic Crisp sets
(which is a generalization of Crisp sets) on the classical probability,
from the construction of the Neutrosophic sample space to the
Neutrosophic crisp events reaching the definition of Neutrosophic
classical probability for these events. Then we offer some of the
properties of this probability, in addition to some important theories
related to it. We also come into the definition of conditional
probability and Bayes theory according to the Neutrosophic Crisp
sets, and eventually offer some important illustrative examples. This
is the link between the concept of Neutrosophic for classical events
and the neutrosophic concept of fuzzy events. These concepts can
be applied in computer translators and decision-making theory.

In this paper, we propose the use of causal inference techniques for survival function estimation and prediction for subgroups of the data, upto individual units. Tree ensemble methods, specifically random forests were modified for this purpose. A real world healthcare dataset was used with about 1800 patients with breast cancer, which has multiple patient covariates as well as disease free survival days (DFS) and a death event binary indicator (y). We use the type of cancer curative intervention as the treatment variable (T=0 or 1, binary treatment case in our example).
The algorithm is a 2 step approach. In step 1, we estimate heterogeneous treatment effects using a causalTree with the DFS as the dependent variable. Next, in step 2, for each selected leaf of the causalTree with distinctly different average treatment effect (with respect to survival), we fit a survival forest to all the patients in that leaf, one forest each for treatment T=0 as well as T=1 to get estimated patient level survival curves for each treatment (more generally, any model can be used at this step).
Then, we subtract the patient level survival curves to get the differential survival curve for a given patient, to compare the survival function as a result of the 2 treatments.
The path to a selected leaf also gives us the combination of patient features and their values which are causally important for the treatment effect difference at the leaf.

Objective: Parvovirus B19 appears to be associated with several diseases, one among those appears to be systemic sclerosis. Still, there is no evidence of a causal link be-tween parvovirus B19 and systemic sclerosis.
Methods: To explore the cause-effect relationship between Parvovirus B19 and sys-temic sclerosis, a systematic review and re-analysis of studies available and suitable was performed. The method of the conditio sine qua non relationship was used to proof the hypothesis without Parvovirus B19 infection no systemic sclerosis. The mathematical formula of the causal relationship k was used to proof the hypothesis, whether there is a cause effect relationship between Parvovirus B19 and systemic sclerosis. Significance was indicated by a p-value of less than 0.05
Result: The data analyzed support the Null-hypothesis that without Parvovirus B19 infection no systemic sclerosis. In the same respect, the studies analyzed provide evi-dence of a (highly) significant cause effect relationship between Parvovirus B19 and systemic sclerosis.
Conclusion: This study supports the conclusion that Parvovirus B19 is the cause of systemic sclerosis.

In this paper, we propose a novel nonconvex penalty function for compressed sensing using integral convolution approximation. It is well known that an unconstrained optimization criterion based on $\ell_1$-norm easily underestimates the large component in signal recovery. Moreover, most methods either perform well only under the measurement matrix satisfied restricted isometry property (RIP) or the highly coherent measurement matrix, which both can not be established at the same time. We introduce a new solver to address both of these concerns by adopting a frame of the difference between two convex functions with integral convolution approximation. What's more, to better boost the recovery performance, a weighted version of it is also provided. Experimental results suggest the effectiveness and robustness of our methods through several signal reconstruction examples in term of success rate and signal-to-noise ratio (SNR).

Objective: Accumulating evidence indicates that the gut microbiome has an increas-ingly important role in human disease and health. Fusobacterium nucleatum has been identified in several studies as the leading gut bacterium which is present in colorectal cancer (CRC). Still it is not clear if Fusobacterium plays a causal role.
Methods: To explore the cause-effect relationship between Fusobacterium nucleatum and colorectal cancer, a systematic review and re-analysis of studies published was performed. The method of the conditio sine qua non relationship was used to proof the hypothesis without Fusobacterium nucleatum infection no colorectal cancer. The mathematical formula of the causal relationship k was used to proof the hypothesis, whether there is a cause effect relationship between Fusobacterium nucleatum and colorectal cancer. Significance was indicated by a p-value of less than 0.05
Result: The data analyzed support the Null-hypothesis that without Fusobacterium nucleatum infection no colorectal cancer. In the same respect, the studies analyzed provide highly significant cause effect relationship between Fusobacterium nucleatum and colorectal cancer.
Conclusion: The findings of this study suggest that Fusobacterium (nucleatum) is the cause of colorectal cancer.

Biased statistics can arise from computational errors, belief in non-existent or unproven correlations ...or acceptance of premises proven invalid scientifically.
It is the latter that will be examined here for the case of human life expectancy, whose values are well-known...and virtually never challenged as to their basic assumptions.
Whether the false premises are accidental, a case of overlooking the obvious...or if they may be deliberate distortions serving a subliminal agenda.... is beyond the scope of this analysis.

Latent Dirichlet Allocation (LDA) is a generative model describing the observed data as being composed of a mixture of underlying unobserved topics, as introduced by Blei et al. (2003). A key hyperparameter of LDA is the number of underlying topics *k*, which must be estimated empirically in practice. Selecting the appropriate value of *k* is essentially selecting the correct model to represent the data; an important issue concerning the goodness of fit. We examine in the current work a series of metrics from literature on a quantitative basis by performing benchmarks against a generated dataset with a known value of *k* and evaluate the ability of each metric to recover the true value, varying over multiple levels of topic resolution in the Dirichlet prior distributions. Finally, we introduce a new metric and heuristic for estimating kand demonstrate improved performance over existing metrics from the literature on several benchmarks.

Viewing the random motions of objects, an observer might think it is 50-50 chances that an object would move toward or away. It might be intuitive, however, it is far from the truth. This study derives the probability functions of Doppler blueshift and redshift effect of signal detection.
The fact is, Doppler redshift detection is highly dominating in space, surface, and linear observation. Under the conditions of no quality loss of radiation over distance, and the observer has perfect vision; It is more than 92% probability of detecting redshift, in three-dimensional observation, 87% surface, and 75\% linear. In cosmic observation, only 7.81% of the observers in the universe will detect blueshift of radiations from any object, on average. The remaining 92.19% of the observers in the universe will detect redshift. It it universal for all observers, aliens or Earthlings at all locations of the universe.

Many applications in signal processing require the estimation of some parameters of interest given a set of observed data. More specifically, Bayesian inference needs the computation of a-posteriori estimators which are often expressed as complicated multi-dimensional integrals. Unfortunately, analytical expressions for these estimators cannot be found in most real-world applications, and Monte Carlo methods are the only feasible approach. A very powerful class of Monte Carlo techniques is formed by the Markov Chain Monte Carlo (MCMC) algorithms. They generate a Markov chain such that its stationary distribution coincides with the target posterior density. In this work, we perform a thorough review of MCMC methods using multiple candidates in order to select the next state of the chain, at each iteration. With respect to the classical Metropolis-Hastings method, the use
of multiple try techniques foster the exploration of the sample space. We present different Multiple Try Metropolis schemes, Ensemble MCMC methods, Particle Metropolis-Hastings
algorithms and the Delayed Rejection Metropolis technique. We highlight limitations, benefits, connections and dierences among the different methods, and compare them by numerical simulations.

Objective: Many times a positive relationship between Helicobacter pylori infection and gastric cancer has been reported, yet findings are inconsistent.
Methods: A literature search in PubMed was performed to re-evaluate the relationship between Helicobacter pylori (HP) and carcinoma of human stomach. Case control studies with a least 500 participants were consider for a review and meta-analysis. The meta-/re-analysis was conducted using conditio-sine qua non relationship and the causal relationship k. Significance was indicated by a p-value of less than 0.05.
Result: All studies analyzed provide impressive evidence of a cause effect relationship between H. pylori and gastric cancer (GC). Two very great studies were able to make the proof that H. pylori is a necessary condition of human gastric cancer. In other words, without H. pylori infection no human gastric cancer.
Conclusion: Our findings indicate that Helicobacter pylori (H. pylori) is the cause of gastric carcinoma.

Objective: A series of different studies detected Human papillomavirus (HPV) in malignant and nonmalignant prostate tissues. However, the results of studies on the relationship between HPV infections and prostate cancer (PCa) remain controversial.
Methods: A systematic review and re-analysis of some polymerase-chain reaction (PCR) based case-control studies was performed aimed to answer the following question: Is there a cause effect relationship between human papillomavirus (HPV) and prostatic cancer? The method of the conditio per quam relationship was used to proof the hypothesis: if presence of human papillomavirus (HPV) in human prostate tissues then presence of prostate carcinoma. The mathematical formula of the causal relationship k was used to proof the hypothesis, whether there is a cause effect relationship between human papillomavirus (HPV) and prostate cancer.

Result: Only one of the studies analyzed failed to provide evidence that there is a cause-effect relationship between human papillomavirus (HPV) and prostate cancer. Two studies were highly significant on this point. The majority of the studies analyzed support the hypothesis that human papillomavirus (HPV) is a sufficient condition of prostate cancer.

Herein we present the “surround” function, which is intended to produce a set of “surround codes” which enhance the sparsity of integer sets which have discrete derivatives of lesser Shannon entropy than the sets themselves. In various cases, the surround function is expected to provide further entropy reduction beyond that provided by straightforward delta (difference) encoding alone.

We then present the simple concept of “densification”, which facilitates the elimination of entropy overhead due to masks (symbols) which were considered possible but do not actually occur in a given mask list (set of symbols).

Finally we discuss the ramifications of these techniques for the sake of enhancing the speed and sensitivity of various entropy scans.

Background: The aim of this study is to work out a possible relationship between hu-man papillomavirus (HPV) and malignant melanoma.
Objectives: This systematic review and re-analysis of Roussaki-Schulze et al. availa-ble retrospective study of twenty-eight melanoma biopsy specimens and of the control group of 6 patients is performed so that some new inference can be drawn.
Materials and methods: Roussaki-Schulze et al. obtained data from twenty-eight human melanoma biopsy specimens and from six healthy individuals. The presence and types of HPV DNA within biopsy specimens was determined by polymerase chain reaction (PCR). Statistical Analysis: In contrast to Roussaki-Schulze et al., the meth-od of the conditio per quam relationship was used to proof the hypothesis that the presence of human papillomavirus (HPV) guarantees the presence of malignant mel-anoma. In other words, if human papillomavirus (HPV) is present, then malignant melanoma must also be present. The mathematical formula of the causal relationship k was used to proof the hypothesis, whether there is a cause effect relationship be-tween human papillomavirus (HPV) and malignant melanoma. Significance was indi-cated by a p-value of less than 0.05.
Results: Based on the data published by Roussaki-Schulze et al. we were able to make evidence that the presence of human papillomavirus (HPV) guarantees the presence of malignant melanoma. In other words, human papillomavirus (HPV) is a conditio per quam of malignant melanoma. Contrary to expectation, the data of Roussaki-Schulze et al. based on a very small sample size failed to provide significant evidence that human papillomavirus (HPV) is a cause or the cause of malignant melanoma.
Conclusions: Human papillomavirus (HPV) is a conditio per quam of malignant melanoma.

The Jensen-Shannon divergence (JSD) quantifies the “information distance” between a pair of probability distributions. (A more generalized version, which is beyond the scope of this paper, is given in [1]. It extends this divergence to arbitrarily many such distributions. Related divergences are presented in [2], which is an excellent summary of existing work.)
A couple of novel applications for this divergence are presented herein, both of which involving sets of whole numbers constrained by some nonzero maximum value. (We’re primarily concerned with discrete applications of the JSD, although it’s defined for analog variables.) The first of these, which we can call the “Jensen-Shannon divergence transform” (JSDT), involves a sliding “sweep window” whose JSD with respect to some fixed “needle” is evaluated at each step as said window moves from left to right across a superset called a “haystack”.
The second such application, which we can call the “Jensen-Shannon exodivergence transform” (JSET), measures the JSD between a sweep window and an “exosweep”, that is, the haystack minus said window, at all possible locations of the latter. The JSET turns out to be exceptionally good at detecting anomalous contiguous subsets of a larger set of whole numbers.
We then investigate and attempt to improve upon the shortcomings of the JSD and the related Kullback-Leibler divergence (KLD).

Data loss is a big problem in many online monitoring systems due to various reasons. Copula-based approaches are effective imputation methods for missing data imputation; however, such methods are highly dependent on a reliable distribution of missing data. This article proposed a functional regression approach for missing probability density function (PDF) imputation. PDFs are first transformed to a Hilbert space by the log quantile density (LQD) transformation. The transformed results of the response PDFs are approximated by the truncated Karhunen–Loève representation. Corresponding representation in the Hilbert space of a missing PDF is estimated by a vector-on-function regression model in reproducing kernel Hilbert space (RKHS), then mapping back to the density space by the inverse LQD transformation to obtain an imputation for the missing PDF. To address errors caused by the numerical integration in the inverse LQD transformation, original PDFs are aided by a PDF of uniform distribution. The effect of the added uniform distribution in the imputed result of a missing PDF can be separated by the warping function-based PDF estimation technique.

We present a review of data types and statistical methods often encountered in astronomy. The aim is to provide an introduction to statistical applications in astronomy for statisticians and computer scientists. We highlight the complex, often hierarchical, nature of many astronomy inference problems and advocate for cross-disciplinary collaborations to address these challenges.

Since publication of NUREG/CR-6850 (EPRI 1011989), EPRI/NRC-RES Fire PRA Methodology for Nuclear Power Facilities in 2005, phenomenological modeling of fire growth to peak heat release rate (HRR) for electrical enclosure fires in nuclear power plant probabilistic risk assessment (PRA) has typically assumed an average 12-minute rise time. One previous analysis using the data from NUREG/CR-6850 from which this estimate derived (Gallucci, “Statistical Characterization of Cable Electrical Failure Temperatures Due to Fire, with Simulation of Failure Probabilities”) indicated that the time to peak HRR could be represented by a gamma distribution with alpha (shape) and beta (scale) parameters of 8.66 and 1.31, respectively. Completion of the test program by the US Nuclear Regulatory Commission (USNRC) for electrical enclosure heat release rates, documented in NUREG/CR-7197, Heat Release Rates of Electrical Enclosure Fires (HELEN-FIRE) in 2016, has provided substantially more data from which to characterize this growth time to peak HRR. From these, the author develops probabilistic distributions that enhance the original NUREG/CR-6850 results for both qualified (Q) and unqualified cables (UQ). The mean times to peak HRR are 13.3 and 10.1 min for Q and UQ cables, respectively, with a mean of 12.4 min when all data are combined, confirming that the original NUREG/CR-6850 estimate of 12 min was quite reasonable.
Via statistical-probabilistic analysis, the author shows that the time to peak HRR for Q and UQ cables can again be well represented by gamma distributions with alpha and beta parameters of 1.88 and 7.07, and 3.86 and 2.62, respectively. Working with the gamma distribution for All cables given the two cable types, the author performs simulations demonstrating that manual non-suppression probabilities, on average, are 30% and 10% higher than the use of a 12-min point estimate when the fire is assumed to be detected at its start and halfway between its start and the time it reaches its peak, respectively. This suggests that adopting a probabilistic approach enables more realistic modeling of this particular fire phenomenon (growth time).

Monte Carlo (MC) methods have become very popular in signal processing during the past decades. The adaptive rejection sampling (ARS) algorithms are well-known MC technique which draw efficiently independent samples from univariate target densities. The ARS schemes yield a sequence of proposal functions that converge toward the target, so that the probability of accepting a sample approaches one. However, sampling from the proposal pdf becomes more computational demanding each time it is updated. We propose the Parsimonious Adaptive Rejection Sampling (PARS) method, where a better trade-off
between acceptance rate and proposal complexity is obtained. Thus, the resulting algorithm is faster than the standard ARS approach.

Importance Sampling (IS) is a well-known Monte Carlo technique that approximates integrals involving a posterior distribution by means of weighted samples. In this work, we study the assignation of a single weighted sample which compresses the information contained in a population of weighted samples. Part of the theory that we present as Group Importance Sampling (GIS) has been already employed implicitly in different works in literature. The provided analysis yields several theoretical and practical consequences. For instance, we discuss the application of GIS into the Sequential Importance Resampling (SIR) framework and show that Independent Multiple Try Metropolis (I-MTM) schemes can be interpreted as a standard Metropolis-Hastings algorithm, following the GIS approach. We also introduce two novel Markov Chain Monte Carlo (MCMC) techniques based on GIS. The first one, named Group Metropolis Sampling (GMS) method, produces a Markov chain of sets of weighted samples. All these sets are then employed for obtaining a unique global estimator. The second one is the Distributed Particle Metropolis-Hastings (DPMH) technique, where different parallel particle filters are jointly used to drive an MCMC algorithm.
Different resampled trajectories are compared and then tested with a proper acceptance probability. The novel schemes are tested in different numerical experiments and compared with several benchmark Monte Carlo techniques. Three descriptive Matlab demos are also provided.

Situational Underlying Value (SUV) arose from an attempt to develop an all-encompassing statistic for measuring “clutchiness” for individual baseball players. It was to be based on the “run expectancy” concept, whereby each base with a certain number of outs is “worth” some fraction of a run. Hitters/runners reaching these bases would acquire the “worth” of that base, with the “worth” being earned by the hitter if he reached a base or advanced a runner, or the runner himself if he advanced “on his own” (e.g., stolen base, wild pitch). After several iterations, the version for SUV Baseball presented herein evolved, and it is demonstrated via two games. Subsequently, the concept was extended to professional football and NCAA Men’s Basketball, both with two example games highlighting selected individual players. As with Major League Baseball, these are team games where individual performance may be hard to gauge with a single statistic. This is the goal of SUV, which can be used as a measure both for the team and individual players.

The deployment of sensors that characterize the trajectory of pitches and batted balls in three dimensions provides the opportunity to assign an intrinsic value to a pitch that depends on its physical properties and not on its observed outcome. We exploit this opportunity by utilizing a Bayesian framework to map five-dimensional PITCHf/x
velocity, movement, and location vectors to pitch intrinsic values. HITf/x data is used by
the model to obtain intrinsic quality-of-contact values for batted balls that are invariant to the defense, ballpark, and atmospheric conditions. Separate mappings are built to accommodate the effects of count and batter/pitcher handedness. A kernel method is used to generate nonparametric estimates for the component probability density functions in Bayes theorem while cross-validation enables the model to adapt to the size and structure of the data.

This paper analyses the question how to systematically reach the top flight of soccer prediction leagues. In a first step several forecast models are compared and it is shown how most models can be related to the Poisson model. Some of the relations are new. Additionally a method has been developed which allows to numerically evaluate the outcome probabilities of soccer championships instead of simulation. The main practical result for the example of the 2014 soccer World Championship was that the forecast models were significantly better than the human participants of a large public prediction league. However the results between the forecast models were small, both qualitatively and quantitatively. But it is quite unlikely that a large prediction league will be won by a forecast model although the forecast models almost all belonged to the top flight of the prediction league.

SUV – Situational Underlying Value – for professional baseball (MLB) is a concept based on the more traditional one of “run expectancy.” This is a statistical estimate of the number of runs expected to result from a base runner or multiple runners given his/their presence at a particular base, or bases, and the number of outs in an inning. Numerous baseball websites discuss this concept; one can find dozens more with a simple internet search on “run expectancy.”
SUV for professional football (NFL) is not as readily conceived as that for baseball, although the concept of each position on the field with down and yards to go has been examined for the possibility of assigning point values (from here on referred to as SUVs). Quantification of this concept is taken from “Expected Points and Expected Points Added Explained,” by Brian Burke, December 7, 2014.
Example applications to a pair of professional baseball games (MLB) and pair of professional football games (NFL) are included that illustrate how the SUV is used.

Automatic differentiation is a powerful collection of software tools that are invaluable in many areas including statistical computing. It is well known that automatic differentiation techniques can be applied directly by a programmer in a process called hand coding. However, the advantages of hand coding with certain applications are less appreciated, but these advantages are of paramount importance to statistics in particular. Based on the present literature, the variance component problem using restricted maximum likelihood is an example where hand coding derivatives was very useful relative to automatic or algebraic approaches. Some guidelines for hand coding backward derivatives are also provided, and emphasis is given to techniques for reducing space complexity and computing second derivatives.

In computer science, a selection algorithm is an algorithm for finding the kth smallest number in a list or array; such a number is called the kth order statistic. This includes the cases of finding the minimum, maximum, and median elements. There are O(n) (worst-case linear time) selection algorithms, and sublinear performance is possible for structured data; in the extreme, O(1) for an array of sorted data. Selection is a subproblem of more complex problems like the nearest neighbor and shortest path problems. Many selection algorithms are derived by generalizing a sorting algorithm, and conversely some sorting algorithms can be derived as repeated application of selection.
This new algorithm although has worst case of O(n^2), the average case is of near linear time for an unsorted list.

Epstein-Barr Virus (EBV) has been widely proposed as a possible candidate virus for the viral etiology of human breast cancer, still the most common malignancy affecting females worldwide. Due to possible problems with PCR analyses (contamination), the lack of uniformity in the study design and insufficient mathematical/statistical methods used by the different authors, findings of several EBV (polymerase chain reaction (PCR)) studies contradict each other making it difficult to determine the EBV etiology for breast cancer. In this present study, we performed a re-investigation of some of the known studies. To place our results in context, this study support the hypothesis that EBV is a cause of human breast cancer.

Despite intensive study, the role of Epstein-Barr virus in Hodgkin's lymphoma remains enigmatic. It is the purpose of this publication to make the proof the Epstein-Barr virus is a main cause of Hodgkin’s lymphoma (k=+0,739814235, p Value = 0,000000000000138).

Background: Many studies documented an association between a Helicobacter pylori infection and the development of human gastric cancer. None of these studies were able to identify Helicobacter pylori as a cause or as the cause of human gastric cancer. The basic relation between gastric cancer and Helicobacter pylori still remains uncer-tain.
Objectives: This systematic review and re-analysis of Naomi Uemura et al. available long-term, prospective study of 1526 Japanese patients is performed so that some new and meaningful inference can be drawn.
Materials and Methods: Data obtained by Naomi Uemura et al. who conducted a long-term, prospective study of 1526 Japanese patients with a mean follow up about 7.8 years and endoscopy at enrolment and in the following between one and three years after enrolment were re-analysed.
Statistical analysis used:
The method of the conditio sine qua non relationship was used to proof the hypothesis without a helicobacter pylori infection no development of human gastric cancer. The mathematical formula of the causal relationship was used to proof the hypothesis, whether there is a cause effect relationship between a helicobacter pylori infection and human gastric cancer. Significance was indicated by a P value of less than 0.05.
Results:
Based on the data published by Uemura et al. we were able to make evidence that without a helicobacter pylori infection no development of human gastric cancer. In other words, a Helicobacter pylori infection is a conditio sine qua non of human gastric cancer. In the same respect, the data of Uemura et al. provide a significant evidence that a helicobacter pylori infection is the cause of human gastric cancer.
Conclusions:
Without a Helicobacter pylori infection no development of human gastric cancer. Hel-icobacter pylori is the cause (k=+0,07368483, p Value = 0.00399664) of human gastric cancer.

Objective.
Many studies presented some evidence that EBV might play a role in the pathogenesis of rheumatoid arthritis. Still, there are conflicting reports concerning the existence of EBV in the synovial tissue of patients suffering from rheumatoid arthritis.
Material and methods.
Takeda et al. designed a study to detected EBV DNA is synovial tissues obtained at synovectomy or arthroplasty from 32 patients with rheumatoid arthritis (RA) and 30 control patients (no rheumatoid arthritis). In this study, the data as published by Takeda et al. were re-analysed.
Results.
EBV infection of human synovial tissues is a condition per quam of rheumatoid arthritis. And much more than this. There is a highly significant causal relationship between an EBV infection of human synovial tissues and rheumatoid arthritis (k= +0,546993718, p-value = 0,00001655).
Conclusion.
These findings suggest that EBV infection of human synovial tissues is a main cause of rheumatoid arthritis.

This paper analyses the data for the masses of elementary particles provided by the Particles Data Group (PDG). It finds evidence that the best mass estimates are not based solely on statistics but also on overall consistency, that sometimes results in skewed minimum and maximum mass limits. The paper also points out to some other quirks that result in minimum and maximum mass limits which are far from the statistical standard deviation. A statistical method is proposed to compute the standard deviation in such cases and when PDG does not provide any limits.

During the last decades, Power-law distributions played significant roles in analyzing the topology of scale-free (SF) networks. However, in the observation of degree distributions of practical networks and other unequal distributions such as wealth distribution, we uncover that, instead of monotonic decreasing, there exists a peak at the beginning of most real distributions, which cannot be accurately described by a Power-law. In this paper, in order to break the limitation of the Power-law distribution, we provide detailed derivations of a novel distribution called Subnormal distribution from evolving networks with variable
elements and its concrete statistical properties. Additionally, imulations of fitting the subnormal distribution to the degree distribution of evolving networks, real social network, and
personal wealth distribution are displayed to show the fitness of proposed distribution.

GabrielEigen is a simple deterministic imputation system without structural or distributional assumptions, which uses a mixture of regression and lower-rank approximation of a matrix based on its singular value decomposition. We provide multiple imputation alternatives (MI) based on this system, by adding random quantities and generating approximate confidence intervals with different widths to the imputations using cross-validation (CV). These methods are assessed by a simulation study using real data matrices in which values are deleted randomly at different rates, and also in a case where the missing observations have a systematic pattern. The quality of the imputations is evaluated by combining the variance between imputations (Vb) and their mean squared deviations from the deleted values (B) into an overall measure (Tacc). It is shown that the best performance occurs when the interval width matches the imputation error associated with GabrielEigen.

Monte Carlo methods are essential tools for Bayesian inference. Gibbs sampling is a well-known Markov chain Monte Carlo (MCMC) algorithm, extensively used in statistical signal processing, machine learning and statistics, employed to draw samples from complicated high-dimensional posterior distributions. The key point for the successful application of the Gibbs sampler is the ability to draw efficiently from the full-conditional pdfs. In the general case, this is not possible and it requires the generation of auxiliary samples that are wasted, since they are not used in the final estimators. In this work, we show that these auxiliary samples can be employed within the Gibbs estimators, improving their efficiency with no extra cost. This novel scheme arises naturally after pointing out the relationship between the Gibbs sampler and the chain rule used for sampling purpose. Numerical simulations confirm the excellent performance of the novel scheme.

The main aim of the present book is to suggest some improved estimators using auxiliary and attribute information in case of simple random sampling and stratified random sampling and some inventory models related to capacity constraints.
This volume is a collection of five papers, written by six co-authors (listed in the order of the papers): Dr. Rajesh Singh, Dr. Sachin Malik, Dr. Florentin Smarandache, Dr. Neeraj Kumar, Mr. Sanjey Kumar & Pallavi Agarwal.
In the first chapter authors suggest an estimator using two auxiliary variables in stratified random sampling for estimating population mean.
In second chapter they proposed a family of estimators for estimating population means using known value of some population parameters.
In Chapter third an almost unbiased estimator using known value of some population parameter(s) with known population proportion of an auxiliary variable has been used.
In Chapter four the authors investigates a fuzzy economic order quantity model for two storage facility. The demand, holding cost, ordering cost, storage capacity of the own - warehouse are taken as trapezoidal fuzzy numbers.
In Chapter five a two-warehouse inventory model deals with deteriorating items, with stock
dependent demand rate and model affected by inflation under the pattern of time value of
money over a finite planning horizon. Shortages are allowed and partially backordered
depending on the waiting time for the next replenishment. The purpose of this model is to
minimize the total inventory cost by using the genetic algorithm.
This book will be helpful for the researchers and students who are working in the field of sampling techniques and inventory control.

Unlike other common transcendental functions such as log and sine, James Stirling's convergent series for the loggamma (“logΓ”) function suggests no obvious method by which to ascertain meaningful bounds on the error due to truncation after a particular number of terms. (“Convergent” refers to the fact that his original formula appeared to converge, but ultimately diverged.) As such, it remains an anathema to the interval arithmetic algorithms which underlie our confidence in its various numerical applications.
Certain error bounds do exist in the literature, but involve branches and procedurally generated rationals which defy straightforward implementation via interval arithmetic.
In order to ameliorate this situation, we derive error bounds on the loggamma function which are readily amenable to such methods.

Ashkenazim Jews (AJ) comprise roughly 30% of Nobel Prize winners, ‘elite institute’ faculty, etc. Mean AJ intelligence quotients (IQ) fail explaining this, because AJ are only 2.2% of the US population. The growing anti-Semitic right wing supports conspiracy theories with this. However, deviations depend on means. This lifts the right wing of the AJ IQ distribution. Alternative mechanisms such as intellectual AJ culture or in-group collaboration, even if real, must be regarded as included through their IQ-dependence. Antisemitism is thus opposed in its own domain of discourse; it is an anti-intelligence position inconsistent with eugenics.

We propose a new methodology for multiple imputation when faced with missing data in multi-environmental trials with genotype-by-environment interaction, based on the imputation system developed by Krzanowski that uses the singular value decomposition (SVD) of a matrix. Several different iterative variants are described; differential weights can also be included in each variant to represent the influence of different components of SVD in the imputation process. The methods are compared through a simulation study based on three
real data matrices that have values deleted randomly at different percentages, using as measure of overall accuracy a combination of the variance between imputations and their mean square deviations relative to the deleted values. The best results are shown by two of the iterative schemes that use weights belonging to the interval [0.75, 1]. These schemes provide imputations that have higher quality when compared with other multiple imputation methods based on the Krzanowski method.

In multi-environment trials it is common to measure several response variables or attributes to determine the genotypes with the best characteristics. Thus it is important to have techniques to analyse multivariate multi-environment trial data. The main objective is to complement the literature on two multivariate techniques, the mixture maximum likelihood method of clustering and three-mode principal component analysis, used to analyse genotypes, environments and attributes simultaneously. In this way, both global and detailed statements about the performance of the genotypes can be made, highlighting the benefit of using three-way data in a direct way and providing an alternative analysis for researchers. We illustrate using sunflower data with twenty genotypes, eight environments and three attributes. The procedures provide an analytical procedure which is relatively easy to apply and interpret in order to describe the patterns of performance and associations in multivariate multi-environment trials.

What makes a good prediction good? Generally, the answer is thought to be a faithful accounting of both tangible and intangible factors. Among sports teams, it is thought that if you get enough of the tangible factors (e.g. roster, prior performance, schedule) correct, then the predictions will be correspondingly accurate. While there is a role for intangible factors, they are thought to gum up the works, so to speak. Here, I start with the hypothesis that the best and worst teams in a league or tournament are easy to predict relative to teams with average performance. Data from the 2013 MLB and NFL seasons plus data from the 2014 NCAA Tournament were used. Using a model-free approach, data representing various aspects of competition reveal that mainly the teams predicted to perform the worst actually conform to expectation. The reasons for this are then discussed, including the role of shot noise on performance driven by tangible factors.

Mobile crowdsensing can facilitate environmental surveys by leveraging sensor equipped mobile devices that carry out measurements covering a wide area in a short time, without bearing the costs of traditional field work. In this paper, we
examine statistical methods to perform an accurate estimate of the mean value of an environmental parameter in a region, based on such measurements. The main focus is on estimates produced by taking a "snapshot" of the mobile device readings at a random instant in time. We compare stratified sampling with different stratification weights to sampling without stratification, as well as an appropriately modified version of systematic sampling. Our main result is that stratification with weights proportional to stratum areas can produce significantly smaller bias, and gets arbitrarily close to the true area average as the number of mobiles and the number of strata increase. The performance of the methods is evaluated for an application scenario where we estimate the mean area temperature in a linear region that exhibits the so-called *Urban Heat Island* effect, with mobile users moving in the region according to the Random Waypoint Model.

In this work, we design an efficient Monte Carlo
scheme for diffusion estimation, where global and local parameters are involved in a unique inference problem. This
scenario often appears in distributed inference problems in
wireless sensor networks. The proposed scheme uses parallel local MCMC chains and then an importance sampling (IS) fusion for obtaining an efficient estimation of the global parameters. The resulting algorithm is simple and flexible. It can be easily applied iteratively, or extended in a sequential framework. In order to apply the novel scheme, the only assumption required about the model is that the measurements are conditionally independent given the related parameters.

The Sequential Importance Resampling (SIR) method is the core of the Sequential Monte Carlo (SMC) algorithms (a.k.a., particle filters). In this work, we point out a suitable choice for weighting properly a resampled particle. This observation entails several theoretical and practical consequences, allowing also the design of novel sampling schemes. Specifically, we describe one theoretical result about the sequential estimation of the marginal likelihood. Moreover, we suggest a novel resampling procedure for SMC algorithms called partial resampling, involving only a subset of the current cloud of particles. Clearly, this scheme attenuates the additional variance in the Monte Carlo estimators generated by the use of the resampling.

The Effective Sample Size (ESS) is an important measure of efficiency of Monte Carlo methods such as Markov Chain Monte Carlo (MCMC) and Importance Sampling (IS) techniques. In IS context, an approximation of the theoretical ESS definition is widely applied, $\widehat{ESS}$, involving the sum of the squares of the normalized importance weights. This formula $\widehat{ESS}$ has become an essential piece within Sequential Monte Carlo (SMC) methods using adaptive resampling procedures. The expression $\widehat{ESS}$ is related to the Euclidean distance between the probability mass described by the normalized weights and the discrete uniform probability mass function (pmf). In this work, we derive other possible ESS functions based on different discrepancy measures between these pmfs. Several examples are provided involving, for instance, the geometric and harmonic means of the weights, the discrete entropy (including the perplexity measure, already proposed in literature) and the Gini coefficient. We list five requirements which a generic ESS function should satisfy, allowing us to classify different ESS measures. We also compare the most promising ones by means of numerical simulations.

Many signal processing applications require performing statistical inference on large datasets, where computational and/or memory restrictions become an issue. In this big data setting, computing an exact global centralized estimator is often unfeasible. Furthermore, even when approximate numerical solutions (e.g., based on Monte Carlo methods) working directly on the whole dataset can be computed, they may not provide a satisfactory performance either. Hence, several authors have recently started considering distributed inference approaches, where the data is divided among multiple workers (cores, machines or a combination of both). The computations are then performed in parallel and the resulting distributed or partial estimators are finally combined to approximate the intractable global estimator. In this paper, we focus on the scenario where no communication exists among the workers, deriving efficient linear fusion rules for the combination of the distributed estimators. Both a Bayesian perspective (based on the Bernstein-von Mises theorem and the asymptotic normality of the estimators) and a constrained optimization view are provided for the derivation of the linear fusion rules proposed. We concentrate on minimum mean squared error (MMSE) partial estimators, but the approach is more general and can be used to combine any kind of distributed estimators as long as they are unbiased. Numerical results show the good performance of the algorithms developed, both in simple problems where analytical expressions can be obtained for the distributed MMSE estimators, and in a wireless sensor network localization problem where Monte Carlo methods are used to approximate the partial estimators.

Population Monte Carlo (PMC) sampling methods are powerful tools for approximating distributions of static unknowns given a set of observations. These methods are iterative in nature: at each step they generate samples from a proposal distribution and assign them weights according to the importance sampling principle. Critical issues in applying PMC methods are the choice of the generating functions for the samples and the avoidance of the sample degeneracy. In this paper, we propose three new schemes that considerably improve the performance of the original PMC formulation by allowing for better exploration of the space of unknowns and by selecting more adequately the surviving samples.
A theoretical analysis is performed, proving the superiority of the novel schemes in terms of variance of the associated estimators and preservation of the sample diversity.
Furthermore, we show that they outperform other state of the art algorithms (both in terms of mean square error and robustness w.r.t. initialization) through extensive numerical simulations.

Titans like Bertrand Russell or Karl Pearson warned us to keep our mathematical and statistical hands off causality and at the end David Hume too. Hume's scepticism has dominated discussion of causality in both analytic philosophy and statistical analysis for a long time. But more and more researchers are working hard on this field and trying to get rid of this positions. In so far, much of the recent philosophical or mathematical writing on causation (Ellery Eells (1991), Daniel Hausman (1998), Pearl (2000), Peter Spirtes, Clark Glymour and Richard Scheines (2000), ...) either addresses to Bayes networks, to the counterfactual approach to causality developed in detail by David Lewis, to Reichenbach's Principle of the Common Cause or to the Causal Markov Condition. None of this approaches to causation investigated the relationship between causation and the law of independence to a necessary extent. Nonetheless, the relationship between causation and the law of independence, one of the fundamental concepts in probability theory, is very important. May an effect occur in the absence of a cause? May an effect fail to occur in the presence of a cause? In so far, what does constitute the causal relation? On the other hand, if it is unclear what does constitute the causal relation, maybe we can answer the question, what does not constitute the causal relation. So far, a cause as such can not be independent from its effect and vice versa, if there is a deterministic causal relationship. This publication will prove, that the law of independence defines causation to some extent ex negativo.

The statistical analysis of angular data is typically encountered in biological and geological studies, among several other areas of research. Circular data is the simplest case of this category of data called directional data, where the single response is not scalar, but angular or directional. A statistical analysis pertaining to two dimensional directional data is generally referred to as “Circular Statistics”. In this paper, an attempt is made to review various fundamental concepts of circular statistics and to discuss its applicability in sports science.

Objective: Objective scientific knowledge for many authors more valuable than true subjective belief is determined by research on primary data but a renewed analysis of already recorded or published data is common too. Ever since, an appropriate experimental or study design is an important and often a seriously underappreciated aspect of the informativeness and the scientific value of any (medical) study. The significance of study design for the reliability of the conclusions drawn and the ability to generalize the results from the sample investigated for the whole population cannot be underestimated. In contrast to an inappropriate statistical evaluation of a medical study, it is difficult to correct errors in study design after the study has been completed. Various mathematical aspects of study design are discussed in this article.
Methods: In assessing the significance of a fair study design of a medical study, important measures of publication bias are introduced. Methods of data or publication bias analysis in different types of studies are illustrated through examples with fictive data. Formal mathematical requirements of a fair study design which can and should be fulfilled carefully with regard to the planning or evaluation of medical research are developed.
Results.
Various especially mathematical aspects of a fair study design are discussed in this article in detail. Depending on the particular question being asked, mathematical methods are developed which allow us to recognize data which are self-contradictory and to exclude these data from systematic literature reviews and meta-analyses. As a result, different individual studies can be summed up and evaluated with a higher degree of certainty.
Conclusions
This article is intended to give the reader guidance in evaluating the design of studies in medical research even ex post which should enable the reader to categorize medical studies better and to assess their scientific quality more accurately.

A second order time series model is described, and generalized to the multivariate situation. The model is highly flexible, and is suitable for non-parametric regression, coming with unequal time steps. The resulting K-matrix is described, leading to its possible factorization and differentiation using general purpose software that was recently developed. This makes it possible to estimate variance matrices in the multivariate model corresponding the signal and noise components of the model, by restricted maximum likelihood. A nested iteration algorithm is presented for conducting the maximization, and an illustration of the methods are demonstrated on a 4-variate time series with 89 observations.

A two-dimensional lattice model is described that is able to treat border effects in a coherent way. The model belongs to a class of non-parametric regression models, coming with three smoothness parameters that are estimated from cross validation. The techniques use the K-matrix, which is a typically large and sparse matrix that is also symmetric and indefinite. The K-matrix is subjected to factorization, and algorithmic differentiation, using optimized software, thereby permitting estimation of the smoothness parameters and estimation of the two-dimensional surface. The techniques are demonstrated on real data.

Bayesian models have become very popular over the
last years in several fields such as signal processing, statistics and machine learning. Bayesian inference needs the approximation of complicated integrals involving the posterior distribution. For this purpose, Monte Carlo (MC) methods, such as Markov Chain Monte Carlo (MCMC) and Importance Sampling (IS) algorithms, are often employed. In this work, we introduce theory and practice of a Compressed MC (C-MC) scheme, in order to compress the information contained in a could of samples. CMC is particularly useful in a distributed Bayesian inference framework, when cheap and fast communications with a central processor are required. In its basic version, C-MC is strictly related to the stratification technique, a well-known method used for variance reduction purposes. Deterministic C-MC schemes are also presented, which provide very good performance. The compression problem is strictly related to moment matching approach applied in different filtering methods, often known as Gaussian quadrature rules or sigma-point methods. The connections to herding algorithms and quasi-Monte Carlo perspective are also discussed. Numerical results confirm the benefit of the introduced schemes, outperforming the corresponding benchmark methods.

In this paper, asymptotic expansions of the distributions and densities of powered extremes for Maxwell samples are considered. The results show that the convergence speeds of normalized partial maxima relies on the powered index. Additionally, compared with previous result, the convergence rate of the distribution of powered extreme from Maxwell samples is faster than that of its extreme. Finally, numerical analysis is conducted to illustrate our findings.

Aim: Many studies presented some evidence that EBV might play a role in the pathogenesis of rheumatoid arthritis. Still, there are conflicting reports concerning the existence of EBV in the synovial tissue of patients suffering from rheumatoid arthritis. This systematic review assesses the causal relationship between Epstein-Barr virus (EBV) and rheumatoid arthritis (RA) for gaining a better understanding of the pathogenesis of RA.
Methods: A systematic review and meta-analysis is provided aimed to answer among other questions the following question. Is there a cause effect relationship between Epstein-Barr virus and rheumatoid arthritis? The method of the conditio sine qua non relationship was used to proof the hypothesis without Epstein-Barr virus no rheumatoid arthritis. In other words, if rheumatoid arthritis is present, then Epstein-Barr virus is present too. The mathematical formula of the causal relationship k was used to proof the hypothesis, whether there is a cause effect relationship between Epstein-Barr virus and rheumatoid arthritis. Significance was indicated by a p-value of less than 0.05.
Results: The studies analysed were able to provide convincing evidence that Epstein-Barr virus is a necessary condition (a conditio sine qua non) of rheumatoid arthritis. Furthermore, the studies analysed provide impressive evidence of a cause-effect relationship between Epstein-Barr virus and rheumatoid arthritis.
Conclusion: EBV infection of human synovial tissues is a condition sine qua non, a condition per quam and a conditio sine qua non and conditio per quam of rheumatoid arthritis. In other words, Epstein-Barr virus is the cause of rheumatoid arthritis.

In Situational Underlying Value for Baseball, Football and Basketball – A Statistic (SUV) to Measure Individual Performance in Team Sports, an all-encompassing, overall statistic to measure “clutch” performance by individual players in the team sports of major league baseball, professional football, and NCAA men’s college basketball was developed, called “Situational Underlying Value” (SUV). [1] Based on the concept of “run expectancy,” it assigns an SUV to each base as a function of the number of outs, including a negative value for making an out. There, and in “Proof of Principle” for Situational Underlying Value (SUV) – A Statistic to Measure Clutch Performance by Individuals in the Team Sports of Major League Baseball, [2] it was applied exclusively to hitters and pitchers. Its derivation is explained in Reference 1, with additional discussion provided in Reference 2. Reference 1 provides two example games to show how the SUVs accrue for each team’s hitters and pitchers. The goal of this third work, which includes “Proof of Principle” as in Reference 2, is to track the performance of a team’s individual fielders defensively, including an enhancement to the approach for pitching previously developed in Reference 2, over the same substantial portion of an entire season. One-third of the 2017 season, i.e., 54 games, have again been selected for the Seattle Mariners, starting with Game 002 and tracking every third game up through Game 161. The SUVs are based on the play-by-play descriptions provided in “Baseball Reference,” https://www.baseball-reference.com/. [3] Summary SUV analyses for all 54 games are provided below, with a roll-up of cumulative SUVs every six games. Also, the actual play-by-plays are included for every third game analyzed, starting from Game 005 (i.e., for Games 005, 014, 023, 032, 041, 050, 059, 068, 077, 086, 095, 104, 113, 122, 131, 140, 149 and 158), providing a total for 18 games. For the rest (which are only summarized), the reader should consult Reference 3. There is an important change to the above table for defensive tracking, also applied to the enhanced pitching analysis, namely the reversal of all the SUV signs. This enables “positive” defensive outcomes (outs) to be assigned positive SUVs, while “negative” outcomes (reaching base or advancing) are assigned negative SUVs. The assignment of defensive SUVs is somewhat more involved than that for hitting. Specific assignments, most frequently encountered, are presented below.

The autoregressive and rolling moving average time series models are describe with discrete time steps that may be unequal. The standard time series is described, as well as a two-dimensional spatial process that is separable into two one-dimensional processes. The K-matrix representations for each of these are presented, which can then be subjected to standard matrix handling techniques.

This work supplements and extends the development and initial demonstrations of the use of the SUV statistic for these three team sports by tracking the performance of three specific teams in these three sports over a significant portion of their most recent seasons: (1) for major league baseball, 54 of the 162 games played by the Seattle Mariners in 2017; (2) for professional football, five of the 16 games played by the Seattle Seahawks in 2017; and (3) for NCAA Men’s College Basketball, the five games played by the Loyola of Chicago Ramblers in the 2018 NCAA Division I Men’s Basketball Tournament. The SUV statistics for the players who participated in these games are tracked and accumulated for comparison among themselves and, for those who participated in a significant portion of these games, further compared against the traditional statistics for each team over the entire season (or, in the case of the Loyola of Chicago Ramblers, the complete five games of the Basketball Tournament). The goal is to examine the efficacy of this one overarching statistic, the SUV, in representing player performance “in the clutch” vs. more subjective interpretation of the myriad of different “traditional” statistics currently used. Anomalies between the SUV and “traditional” statistics results are examined and explained, to the extent practicable given the scope of the SUV analysis (partial seasons). Whether or not this effort proves successful is left to the reader’s conclusion based on the results and comparisons performed.

Objective: The relationship between Human cytomegalovirus (HCMV) and glioblastoma multiforme (GBM) is investigated.
Methods: A systematic review and re-analysis of some impressive key studies was conducted aimed to answer the following question. Is there a cause-effect relationship between HCMV and GBM? The method of the conditio sine qua non relationship was used to proof the hypothesis whether the presence of HCMV guarantees the presence of GBM. In other words, without HCMV no GBM The mathematical formula of the causal relationship k was used to proof the hypothesis, whether there is a cause-effect relationship between HCMV and GBM. Significance was indicated by a p-value of less than 0.05.
Results: The studies analysed were able to provide strict evidence that HCMV is a necessary condition (a conditio sine qua non) of GBM. Furthermore, the cause-effect relationship between HCMV and GBM (k = +1, p value < 0,0001) was highly significant.
Conclusion: Without HCMV no GBM. HCMV is the cause of GBM.
Keywords: Cytomegalovirus, Glioblastoma multiforme, Causal relationship

Before proceeding, and lest opponents of nuclear power think this paper lends support to their efforts to shut down the nuclear industry, I must state the following. NFPA 805 will have been successful in that plants transitioning to it will be as safe as or safer than prior to transition. Plants that made no changes will have at least assessed their fire risks and be more knowledgeable of potential weaknesses that could compromise safety. Having found none, they will not have the need for changes. Plants that made effective changes will be safer than before. If you are one who believes the end justifies the means, then this “bottom line” is all that matters and you need read no further. However, if you are one who believes the means are also important, then you are the audience that I address.
I am in no way contending that adoption of NFPA 805 compromised safety – I, too, believe that plants will be as safe or safer as a result of the transition. Why I wrote this paper is to express frustration over the “compromises” allowed by the NRC, and the “short-cuts” and “deviations” taken by the nuclear industry, to fulfill the promise of a “sea change” in fire protection at nuclear power plants through risk-informed, performance-based regulation. And, while no diminution of safety will have occurred, it is possible there were missed opportunities to improve safety if changes might have been made, or different changes substituted for those that were made, if not for these “compromises,” “short-cuts” and “deviations.”
I must confess to being guilty of false optimism in December 2006 when I wrote “perhaps the single achievement most responsible for the improved regulatory environment for fire protection at commercial nuclear power plants has been the modification to 10CFR50.48 that allows licensees to ‘maintain a fire protection program that complies with NFPA 805 as an alternative to complying with [past, purely deterministic regulations]’” (Gallucci, “Thirty-Three Years of Regulating Fire Protection at Commercial U.S. Nuclear Power Plants: Dousing the Flames of Controversy,” Fire Technology, Vol. 45, pp. 355-380, 2009).

BACKGROUND: Cytomegalovirus (CMV) infection has been supposed to play an important role in the pathogenesis of atherosclerosis (AS). Although many authors proved the presence of viral DNA in arterial wall tissue, the role of CMV in the origin and progress of athero-sclerosis still remains unclear and no definite consensus has been reached. Whether CMV may be involved in the development of AS has not yet been established. METHODS: The purpose of this study was to investigate whether CMV and AS are causally related. Literature was searched through the electronic database PubMed. Data were accurately assessed and analyzed. RESULTS: The meta-analysis results showed that CMV infection and AS are causally connected. CONCLUSIONS: Cytomegalovirus is the cause of atherosclerosis. Keywords Cytomegalovirus, atherosclerosis, causal relationship

Successive real-valued measurements of any physical chaotic oscillator can serve as entropy inputs to a random number generator (RNG) with correspondingly many whole numbered outputs of arbitrarily small bias, assuming that no correlation exists between successive such measurements apart from what would be implied by their probability distribution function (AKA the oscillator’s analog “generator”, which is constant over time and thus asymptotically discoverable).
Given some historical measurements (a “snapshot”) of such an oscillator, we can then train the RNG to expect inputs distributed uniformally among the real intervals defined by those measurements and spanning the entire real line. Each interval thus implies an index in sorted order, starting with the leftmost which maps to zero; the RNG does nothing more than to perform this mapping. We can then replace that first oscillator with a second one presumed to abide by the same generator. It would then be possible to characterize the accuracy of that presumption by quantifying the ensuing change in quality of the RNG.
Randomness quality is most accurately expressed via dyspoissonism, which is a normalized equivalent of the log of the number of ways in which a particular distribution of frequencies (occurrence counts) of masks (whole numbers) can occur. Thus the difference in dyspoissonism between the RNG output sets will serve to estimate the information divergence between theirrespective generators, which in turn constitutes a ranking quantifier for the purpose of anomaly detection.

Objective: This systematic review assesses the causal relationship between Mycobac-terium avium subspecies paratuberculosis (MAP) and Crohn’s disease (CD). Methods: A systematic review and meat-analysis of some impressive PCR based stud-ies is provided aimed to answer among other questions the following question. Is there a cause effect relationship between Mycobacterium avium subspecies paratuberculosis and Crohn’s disease? The method of the conditio per quam relationship was used to proof the hypothesis whether the presence of Mycobacterium avium subspecies paratuberculosis guarantees the presence of Crohn’s disease. In other words, if Crohn’s disease is present, then Mycobacterium avium subspecies paratuberculosis is present too. The mathematical formula of the causal relationship k was used to proof the hypothesis, whether there is a cause effect relationship between Mycobacterium avium subspecies paratuberculosis and Crohn’s disease. Significance was indicated by a p-value of less than 0.05. Result: The studies analyzed (number of cases and controls N=1076) were able to pro-vide evidence that Mycobacterium avium subspecies paratuberculosis is a necessary condition (a conditio sine qua non) and sufficicent conditions of Crohn’s disease. Furthermore, the studies analyzed provide impressive evidence of a cause-effect relation-ship between Mycobacterium avium subspecies paratuberculosis and Crohn’s disease. Conclusion: Mycobacterium avium subspecies paratuberculosis is the cause of Crohn’s disease

Yu (2000) described the use of the Gibbs sampler to estimate regression parameters where the information available in the form of depended variables is limited to rank information, and where the linear model applies to the underlying variation beneath the ranks. The approach uses an imputation step, which constitute nested draws from truncated normal distributions where the underlying variation is simulated as part of a broader Bayesian simulation. The method is general enough to treat rank information that represents ties or partial orderings.

Many applications in signal processing require the estimation of some parameters of interest given a set of observed data. More specifically, Bayesian inference needs the computation of a-posteriori estimators which are often expressed as complicated multi-dimensional integrals. Unfortunately, analytical expressions for these estimators cannot be found in most real-world applications, and Monte Carlo methods are the only feasible approach. A very powerful class of Monte Carlo techniques is formed by the Markov Chain Monte Carlo (MCMC) algorithms. They generate a Markov chain such that its stationary distribution coincides with the target posterior density. In this work, we perform a thorough review of MCMC methods using multiple candidates in order to select the next state of the chain, at each iteration. With respect to the classical Metropolis-Hastings method, the use of multiple try techniques foster the exploration of the sample space. We present different Multiple Try Metropolis schemes, Ensemble MCMC methods, Particle Metropolis-Hastings algorithms and the Delayed Rejection Metropolis technique. We highlight limitations, benefits, connections and dierences among the different methods, and compare them by numerical simulations.

Background: The aim of this study is to evaluate the possible relationship between human papillomavirus (HPV) and malignant melanoma.
Objectives: In this systematic review we re-analysed the study of Roussaki-Schulze et al. and the study of La Placa et al. so that some new inferences can be drawn.
Materials and methods: Roussaki-Schulze et al. obtained data from 28 human mel-anoma biopsy specimens and from 6 healthy individuals. La Placa et al. investigated 51 primary melanoma (PM) and in 20 control skin samples. The HPV DNA was de-termined by polymerase chain reaction (PCR).
Statistical Analysis: The method of the conditio per quam relationship was used to proof the hypothesis whether the presence of human papillomavirus (HPV) guarantees the presence of malignant melanoma. In other words, if human papillomavirus (HPV) is present, then malignant melanoma is present too. The mathematical formula of the causal relationship k was used to proof the hypothesis, whether there is a cause effect relationship between human papillomavirus (HPV) and malignant melanoma. Signifi-cance was indicated by a p-value of less than 0.05.
Results: Based on the data as published by Roussaki-Schulze et al. and the data of La Placa et al. the presence of human papillomavirus (HPV) guarantees the presence of malignant melanoma. In other words, human papillomavirus (HPV) is a conditio per quam of malignant melanoma. In contrast to the study of La Placa et al. and contrary to expectation, the study of Roussaki-Schulze et al. which is based on a very small sample size failed to provide evidence of a significant cause effect relationship be-tween human papillomavirus (HPV) and malignant melanoma.
Conclusions: Human papillomavirus (HPV) is a necessary condition of malignant melanoma. Human papillomavirus (HPV) is a cause of malignant melanoma.

The Jensen-Shannon divergence (JSD) quantifies the “information distance” between a pair of probability distributions. (A more generalized version, which is beyond the scope of this paper, is given in [1]. It extends this divergence to arbitrarily many such distributions. Related divergences are presented in [2], which is an excellent summary of existing work.)

A couple of novel applications for this divergence are presented herein, both of which involving sets of whole numbers constrained by some nonzero maximum value. (We’re primarily concerned with discrete applications of the JSD, although it’s defined for analog variables.) The first of these, which we can call the “Jensen-Shannon divergence transform” (JSDT), involves a sliding “sweep window” whose JSD with respect to some fixed “needle” is evaluated at each step as said window moves from left to right across a superset called a “haystack”.

The second such application, which we can call the “Jensen-Shannon exodivergence transform” (JSET), measures the JSD between a sweep window and an “exosweep”, that is, the haystack minus said window, at all possible locations of the latter. The JSET turns out to be exceptionally good at detecting anomalous contiguous subsets of a larger set of whole numbers.

We then investigate and attempt to improve upon the shortcomings of the JSD and the related Kullback-Leibler divergence (KLD).

This work gains a sharp sufficient condition on the block restricted isometry property for the recovery of the sparse signal. Under the assumption, the sparse with block structure can be stably recovered in the present of noisy case and the block sparse signal can be assuredly reconstructed in the noise-free case. Besides, in order to exhibit the condition is sharp, we offer an example. Byproduct, as $t=1$, the result enhances the bound of block restricted isometry constant $\delta_{s|\mathcal{I}}$ in Lin and Li (Acta Math. Sin. Engl. Ser. 29(7): 1401-1412, 2013).

The motivation of this study is to investigate new methods for the calculation of the moment-generating function of the lognormal distribution. Taylor expansion method on the moments of the lognormal suffers from divergence issues, saddle-point approximation is not exact, and integration methods can be complicated. In the present paper we introduce a new probability measure that we refer to as the star probability measure as an alternative approach to compute the moment-generating function of normal variate functionals such as the lognormal distribution.

Since publication of NUREG/CR-6850 (EPRI 1011989), EPRI/NRC-RES Fire PRA Methodology for Nuclear Power Facilities in 2005, phenomenological modeling of fire growth to peak heat release rate (HRR) for electrical enclosure fires in nuclear power plant probabilistic risk assessment (PRA) has typically assumed an average 12-minute rise time. [1] One previous analysis using the data from NUREG/CR-6850 from which this estimate derived (Gallucci, “Statistical Characterization of Cable Electrical Failure Temperatures Due to Fire, with Simulation of Failure Probabilities”) indicated that the time to peak HRR could be represented by a gamma distribution with alpha (shape) and beta (scale) parameters of 8.66 and 1.31, respectively. [2] Completion of the test program by the US Nuclear Regulatory Commission (USNRC) for electrical enclosure heat release rates, documented in NUREG/CR-7197, Heat Release Rates of Electrical Enclosure Fires (HELEN-FIRE) in 2016, has provided substantially more data from which to characterize this growth time to peak HRR. [3] From these, the author develops probabilistic distributions that enhance the original NUREG/CR-6850 results for both qualified (Q) and unqualified cables (UQ). The mean times to peak HRR are 13.3 and 10.1 min for Q and UQ cables, respectively, with a mean of 12.4 min when all data are combined, confirming that the original NUREG/CR-6850 estimate of 12 min was quite reasonable.
Via statistical-probabilistic analysis, the author shows that the time to peak HRR for Q and UQ cables can again be well represented by gamma distributions with alpha and beta parameters of 1.88 and 7.07, and 3.86 and 2.62, respectively. Working with the gamma distribution for All cables given the two cable types, the author performs simulations demonstrating that manual non-suppression probabilities, on average, are 30% and 10% higher than the use of a 12-min point estimate when the fire is assumed to be detected at its start and halfway between its start and the time it reaches its peak, respectively. This suggests that adopting a probabilistic approach enables more realistic modeling of this particular fire phenomenon (growth time).

Monte Carlo (MC) methods have become very popular in signal processing during the past decades. The adaptive rejection sampling (ARS) algorithms are well-known MC technique which draw efficiently independent samples from univariate target densities. The ARS schemes yield a sequence of proposal functions that converge toward the target, so that the probability of accepting a sample approaches one. However, sampling from the proposal pdf becomes more computationally demanding each time it is updated. We propose the Parsimonious Adaptive Rejection Sampling (PARS) method, where an efficient trade-off between acceptance rate and proposal complexity is obtained. Thus, the resulting algorithm is faster than the standard ARS approach.

Distributions play a very important role in many applications. Inspired by the newly developed warping transformation of distributions, an indirect nonparametric distribution to distribution regression method is proposed in this article for distribution prediction. Additionally, a hybrid approach by fusing the predictions respectively obtained by the proposed method and the conventional method is further developed for reducing risk when the predictor is contaminated.

Bayesian methods and their implementations by means of sophisticated Monte Carlo techniques have become very popular in signal processing over the last years. Importance
Sampling (IS) is a well-known Monte Carlo technique that approximates integrals involving a posterior distribution by means of weighted samples. In this work, we study the assignation of a single weighted sample which compresses the information contained in a population of weighted samples. Part of the theory that we present as Group Importance Sampling
(GIS) has been employed implicitly in dierent works in the literature. The provided analysis yields several theoretical and practical consequences. For instance, we discuss theapplication of GIS into the Sequential Importance Resampling framework and show that Independent Multiple Try Metropolis schemes can be interpreted as a standard Metropolis-Hastings algorithm, following the GIS approach. We also introduce two novel Markov Chain Monte Carlo (MCMC) techniques based on GIS. The rst one, named Group Metropolis Sampling method, produces a Markov chain of sets of weighted samples. All these sets are
then employed for obtaining a unique global estimator. The second one is the Distributed Particle Metropolis-Hastings technique, where dierent parallel particle lters are jointly used
to drive an MCMC algorithm. Dierent resampled trajectories are compared and then tested with a proper acceptance probability. The novel schemes are tested in dierent numerical experiments such as learning the hyperparameters of Gaussian Processes, two localization problems in a wireless sensor network (with synthetic and real data) and the tracking of vegetation parameters given satellite observations, where they are compared with several benchmark Monte Carlo techniques. Three illustrative Matlab demos are also provided.

Situational Underlying Value (SUV) arose from an attempt to develop an all-encompassing statistic for measuring “clutchiness” for individual baseball players. It was to be based on the “run expectancy” concept, whereby each base with a certain number of outs is “worth” some fraction of a run. Hitters/runners reaching these bases would acquire the “worth” of that base, with the “worth” being earned by the hitter if he reached a base or advanced a runner, or the runner himself if he advanced “on his own” (e.g., stolen base, wild pitch). After several iterations, the version for SUV Baseball presented herein evolved, and it is demonstrated via two games. Subsequently, the concept was extended to professional football and NCAA Men’s Basketball, both with two example games highlighting selected individual players. As with Major League Baseball, these are team games where individual performance may be hard to gauge with a single statistic. This is the goal of SUV, which can be used as a measure both for the team and individual players.

This paper proposes an alternate approach to solve the selection problem and is comparable to best-known algorithm of Quickselect. In computer science, a selection algorithm is an algorithm for finding the Kth smallest number in an unordered list or array. Selection is a subproblem of more complex problems like the nearest neighbor and shortest path problems. Previous known approaches work on the same principle to optimize the sorting algorithm and return the Kth element. This algorithm uses window method to prune and compare numbers to find the Kth smallest element. The average time complexity of the algorithm is linear and has the worst case of O(n^2).

Monte Carlo methods are essential tools for Bayesian inference. Gibbs sampling is a well-known Markov chain Monte Carlo (MCMC) algorithm, extensively used in signal processing, machine learning, and statistics, employed to draw samples from complicated high-dimensional posterior distributions. The key point for the successful application of the Gibbs sampler is the ability to draw efficiently samples from the full-conditional probability density functions. Since in the general case this is not possible, in order to speed up the convergence of the chain, it is required to generate auxiliary samples whose information is eventually disregarded. In this work, we show that these auxiliary samples can be recycled within the Gibbs estimators, improving their efficiency with no extra cost. This novel scheme arises naturally after pointing out the relationship between the standard Gibbs sampler and the chain rule used for sampling purposes. Numerical simulations involving simple and real inference problems confirm the excellent performance of the proposed scheme in terms of accuracy and computational efficiency. In particular we give empirical evidence of performance in a toy example, inference of Gaussian processes hyperparameters, and learning dependence graphs through regression.

Ashkenazim Jews (AJ) comprise roughly 30% of Nobel Prize winners, ‘elite institute’ faculty, etc. Mean intelligence quotients (IQ) fail explaining this, because AJ are only 2.2% of the US population; the maximum possible would be 13% high achievement and needing IQs above 165. The growing anti-Semitic right wing supports conspiracy theories with this. However, standard deviations (SD) depend on means. An AJ-SD of 17 is still lower than the coefficient of variation suggests, but lifts the right wing of the AJ-IQ distribution sufficiently to account for high achievement. We do not assume threshold IQs or smart fractions. Alternative mechanisms such as intellectual AJ culture or ethnocentrism must be regarded as included through their IQ-dependence. Antisemitism is thus opposed in its own domain of discourse; it is an anti-intelligence position inconsistent with eugenics. We discuss the relevance for ‘social sciences’ as sciences and that human intelligence co-evolved for (self-)deception.

Since the publication of NUREG/CR-6850 / EPRI 1011989 in 2005, the US nuclear industry has sought to re-evaluate the default peak heat release rates (HRRs) for electrical enclosure fires typically used as fire modeling inputs to support fire probabilistic risk assessments (PRAs), considering them too conservative. HRRs are an integral part of the fire phenomenological modeling phase of a fire PRA, which consists of identifying fire scenarios which can damage equipment or hinder human actions necessary to prevent core damage. Fire ignition frequency, fire growth and propagation, fire detection and suppression, and mitigating equipment and actions to prevent core damage in the event fire damage still occurred are all parts of a fire PRA. The fire growth and propagation phase incorporates fire phenomenological modeling where HRRs have a key effect. A major effort by the Electric Power Research Institute and Science Applications International Corporation in 2012 was not endorsed by the US Nuclear Regulatory Commission (NRC) for use in risk-informed, regulatory applications. Subsequently the NRC, in conjunction with the National Institute of Standards and Technology, conducted a series of tests for representative nuclear power plant electrical enclosure fires designed to definitively establish more realistic peak HRRs for these often important contributors to fire risk. The results from these tests are statistically analyzed to develop two probabilistic distributions for peak HRR per unit mass of fuel that refine the values from NUREG/CR-6850, thereby providing a fairly simple means by which to estimate peak HRRs from electrical enclosure fires for fire modeling in support of fire PRA. Unlike NUREG/CR-6850, where five different distributions are provided, or NUREG-2178, which now provides 31, the peak HRRs for electrical enclosure fires can be characterized by only two distributions. These distributions depend only on the type of cable, namely qualified vs. unqualified, for which the mean peak HRR per unit mass is 11.3 and 23.2 kW/kg, respectively, essentially a factor of two difference. Two-sided, 90th percentile confidence bounds are 0.091 to 41.15 kW/kg for qualified cables, and 0.027 to 95.93 kW/kg for unqualified cables. From the mean (~70th percentile) upward, the peak HRR/kg for unqualified cables is roughly twice that that for qualified, increasing slightly with higher percentile, an expected phenomenological trend. Simulations using variable fuel loadings are performed to demonstrate how the results from this analysis may be used for nuclear power plant applications.

Mobile crowdsensing can facilitate environmental surveys by leveraging sensor-equipped mobile devices that carry out measurements covering a wide area in a short time, without bearing the costs of traditional field work. In this paper, we examine statistical methods to perform an accurate estimate of the mean value of an environmental parameter in a region, based on such measurements. The main focus is on estimates produced by considering the mobile device readings at a random instant in time. We compare stratified sampling with different stratification weights to sampling without stratification, as well as an appropriately modified version of systematic sampling. Our main result is that stratification with weights proportional to stratum areas can produce significantly smaller bias, and gets arbitrarily close to the true area average as the number of mobiles increases, for a moderate number of strata. The performance of the methods is evaluated for an application scenario where we estimate the mean area temperature in a linear region that exhibits the so-called *Urban Heat Island* effect, with mobile users moving in the region according to the Random Waypoint Model.

In this work, we design an efficient Monte Carlo scheme for a node-specific inference problem where a vector of global parameters and multiple vectors of local parameters are involved. This scenario often appears in inference problems over heterogeneous wireless sensor networks where each node performs observations dependent on a vector of global parameters as well as a vector of local parameters. The proposed scheme uses parallel local MCMC chains and then an importance sampling (IS) fusion step that leverages all the observations of all the nodes when estimating the global parameters. The resulting algorithm is simple and flexible. It can be easily applied iteratively, or extended in a sequential framework.

The Sequential Importance Resampling (SIR) method is the core of the Sequential Monte Carlo (SMC) algorithms (a.k.a., particle filters). In this work, we point out a suitable choice for weighting properly a resampled particle. This observation entails several theoretical and practical consequences, allowing also the design of novel sampling schemes. Specifically, we describe one theoretical result about the sequential estimation of the marginal likelihood. Moreover, we suggest a novel resampling procedure for SMC algorithms called partial resampling, involving only a subset of the current cloud of particles. Clearly, this scheme attenuates the additional variance in the Monte Carlo estimators generated by the use of the resampling.

The Effective Sample Size (ESS) is an important measure of efficiency of Monte Carlo methods such as Markov Chain Monte Carlo (MCMC) and Importance Sampling (IS) techniques. In the IS context, an approximation $\widehat{ESS}$ of the theoretical ESS definition is widely applied, involving the inverse of the sum of the squares of the normalized importance weights. This formula, $\widehat{ESS}$, has become an essential piece within Sequential Monte Carlo (SMC) methods, to assess the convenience of a resampling step. From another perspective, the expression $\widehat{ESS}$ is related to the Euclidean distance between the probability mass described by the normalized weights and the discrete uniform probability mass function (pmf). In this work, we derive other possible ESS functions based on different discrepancy measures between these two pmfs. Several examples are provided involving, for instance, the geometric mean of the weights, the discrete entropy (including the {\it perplexity} measure, already proposed in literature) and the Gini coefficient among others. We list five theoretical requirements which a generic ESS function should satisfy, allowing us to classify different ESS measures. We also compare the most promising ones by means of numerical simulations.

In IS context, an approximation of the theoretical ESS definition is widely applied, $\widehat{ESS}$, involving the sum of the squares of the normalized importance weights. This formula $\widehat{ESS}$ has become an essential piece within Sequential Monte Carlo (SMC) methods using adaptive resampling procedures. The expression $\widehat{ESS}$ is related to the Euclidean distance between the probability mass described by the normalized weights and the discrete uniform probability mass function (pmf). In this work, we derive other possible ESS functions based on different discrepancy measures between these pmfs. Several examples are provided involving, for instance, the geometric and harmonic means of the weights, the discrete entropy (including the perplexity measure, already proposed in literature) and the Gini coefficient.

Population Monte Carlo (PMC) sampling methods are powerful tools for approximating distributions of static unknowns given a set of observations. These methods are iterative in nature: at each step they generate samples from a proposal distribution and assign them weights according to the importance sampling principle. Critical issues in applying PMC methods are the choice of the generating functions for the samples and the avoidance of the sample degeneracy. In this paper, we propose three new schemes that considerably improve the performance of the original PMC formulation by allowing for better exploration of the space of unknowns and by selecting more adequately the surviving samples. A theoretical analysis is performed, proving the superiority of the novel schemes in terms of variance of the associated estimators and preservation of the sample diversity. Furthermore, we show that they outperform other state of the art algorithms (both in terms of mean square error and robustness w.r.t. initialization) through extensive numerical simulations.

Titans like Bertrand Russell or Karl Pearson warned us to keep our mathematical and statistical hands off causality and at the end David Hume too. Hume's scepticism has dominated discussion of causality in both analytic philosophy and statistical analysis for a long time. But more and more researchers are working hard on this field and trying to get rid of this positions. In so far, much of the recent philosophical or mathematical writing on causation (Ellery Eells (1991), Daniel Hausman (1998), Pearl (2000), Peter Spirtes, Clark Glymour and Richard Scheines (2000), ...) either addresses to Bayes networks, to the counterfactual approach to causality developed in detail by David Lewis, to Reichenbach's Principle of the Common Cause or to the Causal Markov Condition. None of this approaches to causation investigated the relationship between causation and the law of independence to a necessary extent. Nonetheless, the relationship between causation and the law of independence, one of the fundamental concepts in probability theory, is very important. May an effect occur in the absence of a cause? May an effect fail to occur in the presence of a cause? In so far, what does constitute the causal relation? On the other hand, if it is unclear what does constitute the causal relation, maybe we can answer the question, what does not constitute the causal relation. So far, a cause as such can not be independent from its effect and vice versa, if there is a deterministic causal relationship. This publication will prove, that the law of independence defines causation to some extent ex negativo.
