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 insert ignore into journalissuearticles values(ME); contaminates the study variable. An empirical study is also car- ried out to judge the merits of proposed estimators
