An Efficient Product Estimator using Harmonic Mean

K. B. Panda, N. Sahoo

Abstract

In this paper a new product estimator has been proposed by exploiting the product estimators due to Srivastava (1983), Agrawal and Jain (1989) and Panda and Sahoo (2015) . The expressions of the bias and mean square error of the proposed estimator, to the first order of approximation, are derived in general form. The new product estimator is found to perform better than its competing estimators from the standpoint of bias and mean square error both in one-phase sampling and twophase sampling under conditions which hold good in practice. The theoretical findings are supported by a numerical illustration.

Keywords

Auxiliary variable, Product estimator, Bias and Mean squared error, Predictive estimation.
