A Modified Dual to Product Estimator of Population Mean in Simple Random Sampling

Abstract

This study is aim to propose the modified dual to product estimator for population mean by adapting Bandyopadhyay’s (1980) estimator for simple random sampling without replacement. We will compare bias and mean square error (MSE) equations obtained with this proposed estimator with Bandyopadhyay’s (1980) estimator, Sharma and Tailor’s (2010) estimator, Choudhury and Singh’s (2012a) estimator, Choudhury and Singh’s (2012b) and Adebola and Adegoke’s (2015). It is found that the proposed estimator is more efficient than these estimators under some conditions. In addition our results are supported by a numerical illustration.
