A New Exponential Approach for Reducing the Mean Squared Errors of the Estimators of Population Mean Using Conventional and Non-Conventional Location Parameters

Abstract

Classes of ratio-type estimators t (say) and ratio-type exponential estimators t_e (say) of the population mean are proposed, and their biases and mean squared errors under large sample approximation are presented. It is the class of ratio-type exponential estimators t_e provides estimators more efficient than the ratio-type estimators.
