Some Improved Estimators for Population Variance Using Two Auxiliary Variables in Double Sampling

Authors: Viplav Kumar Singh, Rajesh Singh, Florentin Smarandache

In this article we have proposed an efficient generalised class of estimator using two auxiliary variables for estimating unknown population variance.We have also extended our problem to the case of two phase sampling. In support of theoretical results we have included an empirical study.
