Classes of estimators for population mean using auxiliary variable in stratified population in the presence of non response
(Taylor and Francis Inc., 2017) B.B. Khare; P.S. Jha
In this article, we have proposed six classes of estimators for population mean using auxiliary variable in stratified population with known population mean in the presence of non response on the study variable. The properties of the proposed class of estimators have been studied for fixed sample size. An empirical study has been given in the support of the proposed classes of the estimator. © 2017 Taylor & Francis Group, LLC.
The general classes of estimators for population mean under stratified two phase random sampling in the presence of non-response
(DAV College, 2020) Rajesh Singh; Supriya Khare; B.B. Khare; P.S. Jha
In this paper, we have proposed six classes of estimators for different cases of non-response for a heterogeneous population under the stratified random sampling using auxiliary information with unknown population mean. The properties of the proposed estimators have been examined and studied for fixed sample size and the members of the proposed classes are also defined. Also, a numerical study has been included in support of the enhanced efficiency of the proposed estimator. © 2020 DAV College. All rights reserved.
