Florentin Smarandache Some Improved Estimators for Population Variance Using Two Auxiliary Variables in Double Sampling
unpublished
In this article we have proposed an efficient generalised class of estimator using two auxiliary variables for estimating unknown population variance 2 y S of study variable y .We have also extended our problem to the case of two phase sampling. In support of theoretical results we have included an empirical study.
