On the Efficiency of a Dual to Ratio-Cum-Product Estimator in Sample Surveys

Abstract

This article suggests a dual to ratio-cum-product estimator for finite population mean that is complementary, in a certain sense, to the commonly used ratiocum-product estimator reported by Singh [4]. The expressions for bias and mean square error of the proposed estimator have been obtained to the first degree of approximation. This study also generalises the work of Srivenkataramana [5] and Bandyopadhyay [1]. To illustrate the results an empirical study is carried out.
