Estimation of Population Mean under Non-Response using Various Imputation Methods for Stratified Population

Abstract

In this paper, estimators of population mean have been proposed using different imputation techniques such as mean, ratio and Exponential method, to deal with the problem of non-response under stratified random sampling scheme. Post Stratification has also been considered and for corresponding point estimators, MSE's and PRE's have been obtained for different Non-response rate.
