摘　　要：In this article,we consider linear transformation using minimum and maximum values of the auxiliary variable and obtain two new ratio estimators.The efficiency of different ratio estimation are compared and then we present the rules of choosing efficient estimator in different situations.In this article, we consider linear transformation using minimum and maximum values of the auxiliary variable and obtain two new ratio estimators.
