Generalized multi-phase regression-type estimators under the effect of measuemnent error to estimate the population variance

Abstract

In this article, we suggest some regression-type estimators for the esti-mation of nite population variance using multi-variate auxiliary infor-mation under multi-phase sampling schemes when measurement error(ME) contaminates the study variable. An empirical study is also car-ried out to judge the merits of proposed estimators
