Adjustment of the Auxiliary Variable(s) for Estimation of a Finite Population Mean

Abstract

In this paper we have worked to weight and transform various estimators by Prasad (1986) and Lui (1991). We have introduced some ratio and ratio type estimators under weighting, transformation and model based approach, environment. We have introduced estimators efficient than estimators proposed by Chakrabarty (1979), Singh and Singh (1997), Singh (2002) and Singh et al. (2006).model based approach; percent relative efficiency; product estimator; ratio estimator; regression estimator; simple mean unit estimator
