Abstract

This paper summarises conventional and alternative estimators of the ratio of two population means of study characters using regression estimator with known population mean of auxiliary character in the presence of non-response. The expression of bias and mean square error of the proposed estimators are derived. After comparison with the corresponding estimators in case of fixed sample size, it is observed that the proposed estimators is always efficient than the existing estimators. An empirical study is carried out to support the theoretical results.
