Estimating the Population Mean in Stratified Population using Auxiliary Information under Non-Response

Authors: Manoj Kr. Chaudhary, V. K. Singh, Rajesh Singh, Florentin Smarandache

The present chapter deals with the study of general family of factor-type estimators for estimating population mean of stratified population in the presence of nonresponse whenever information on an auxiliary variable are available. The proposed family includes separate ratio, product, dual to ratio and usual sample mean estimators as its particular cases and exhibits some nice properties as regards to locate the optimum estimator belonging to the family. Choice of appropriate estimator in the family in order to get a desired level of accuracy even if non-response is high, is also discussed. The empirical study has been carried out in support of the results.
