A Class of Estimators of Population Mean in Case of Post Stratification

Abstract

This paper proposes a class of ratio-cum-product type estimators in case of post-stratification. Particular members of the proposed class of ratio-cum-product type estimators have been identified and studied thoroughly from efficiency point of view. It has been shown that the identified particular estimators are more efficient than the usual unbiased estimator, Ige and Tripathi  estimators , Chouhan  estimators, Tailor et al. estimator and other considered estimators.  An empirical study has been carried out to demonstrate the performance of the proposed estimators.
