Improved Exponential Estimator for Population Variance Using Two Auxiliary Variables

Authors: Rajesh Singh

In this paper, exponential ratio and exponential product type estimators using two auxiliary variables are proposed for estimating unknown population variance S2 y . Problem is extended to the case of two-phase sampling. Theoretical results are supported by an empirical study.
