摘要：In this paper we propose a combined exponential ratio type estimator of finite population mean utilizing information on the auxiliary attribute(s) under non-response. Expressions for bias and MSE of the proposed estimator are derived up to first order of approximation. An empirical study is carried out to observe the performances of the estimators.
