摘要
In the present paper, we study the regression-cum-exponential estimators for estimating ratio of two population means under two different situations. The bias and mean square errors (MSE) are obtained up to the first order of approximation and the conditions for attaining the minimum mean square error of suggested estimators are derived. Theoretical comparisons of suggested estimators with relevant estimators are given. Using real census data sets published by Government of India, an empirical study is carried out to justify the efficiency of the proposed estimators with the conventional as well as the estimators used in practice.
