PPS method of estimation under a transformation. (English) Zbl 1188.62020
Summary: An efficient probability proportional to size (PPS) method of estimation with transformed auxiliary variate is suggested for the situation when there is a negative correlation between the auxiliary variable and the study variable. An analogue to the well known super population model for finite populations is also suggested, using that we compare different estimators. Finally, an empirical investigation of the performance of the proposed estimators is made.
