Some New Estimators of Population Mean Using PPS Sampling

Anita, Shashi Bahl

Abstract: In this study we consider some ratio and product type estimators we calculate bias and mean square error of these estimators. These estimators are compared with usual ratio and product estimators & with mean- per unit. An empirical illustration is also included to justify the practical utility of the proposed estimators.

Keywords: Ratio estimators, product estimators, probability proportional to size sampling Bias, Mean square error
