Abstract

To estimate population mean using multiple supplementary variables in a two-phase sampling set-up, a reducible or generalized product estimator has been constructed. It is assumed that the mean of the primary supplementary variable is unavailable and the means of p other (additional) supplementary variables are easily available. After studying reducibility property of the proposed estimator, some of its desirable statistical properties have been analyzed both theoretically and empirically.
