On estimating the population mean using auxiliary character in stratified random sampling

Abstract

In this article, we propose an exponential estimator in the stratified random sampling taking an auxiliary attribute. Expressions for MSE of the proposed estimators are derived up to first order of approximation and comparison is made with the estimators mentioned herein. By these comparisons, we show that the suggested exponential estimators is found to perform better than the estimators in considered here. These theoretical findings are also supported with the aid of a numerical example.
