摘　　要：The problems of estimating population total in MPPS surveys are considered.There are three models which are appropriate to different correlation coefficient between the study variable y and the auxiliary variable x.Some of the proposed estimators are found superior to Hansen-Hurwitz’s estimator.At last,we suggest a estimator of population correlation coefficient.The problems of estimating population total in MPPS surveys are considered.There are three models which are appropriate to different correlation coefficient between the study variable y and the auxiliary variable x.Some of the proposed estimators are found superior to Hansen-Hurwitz's estimator.At last,we suggest a estimator of population correlation coefficient.
