Abstract

This paper focuses on the estimation problem of population mean by using auxiliary information. By using auxiliary information on first and second moments about zero, a new efficient generalized class of estimators for estimating the finite population mean under two-phase or double sampling scheme have been proposed. The properties of the suggested class of estimators in terms of bias and mean squared error have been studied. The efficiency comparisons have been carried out with respect to the sample mean estimator to establish its superiority. An empirical study is also included as an illustration to justify the results through data.
