Dual to Separate Ratio Type Exponenetial Estimator in Post-Stratification Under Non-Response

G. N. Singh, M. Usman, A. K. Pandey

Abstract



The aim of present study is to propose a dual to separate ratio type exponential estimator to estimate the population mean Y of study variable y in case of post-stratification under non response. The properties of proposed estimator have been discussed and the findings are illustrated numerically through an empirical study which shows that the proposed estimator has better precision over usual unbiased estimator ypst under post-stratification.

Keywords


Study variable, post-stratification, non-response, bias, mean square error.
