Abstract
This study proposes Horvitz-Thompson ratio estimators for the population mean by using the ratio estimators based on regression estimator which is presented in Kadilar and Cingi [1]. Mean square error (MSE)of the proposed Horvitz-Thompson ratio type estimators are obtained and compared with ratio estimators which are presented by Bacanli and Kadilar [2]. The theoretical results are supported by a numerical illustration.The findings demonstrate that the proposed Horvitz-Thompson ratio estimators are more efficient than the estimators of Bacanli and Kadilar [2].
