Estimating the Population Mean in Stratified Random Sampling using Double Sampling Scheme under Non-Response
The present paper focuses on the use of double sampling scheme in stratified random sampling for estimating the population mean in the presence of non-response. We have proposed some separate-type estimators of population mean utilizing the information on an auxiliary variable under the situation in which both study and auxiliary variables are suffered from non-response. The expressions for the biases and mean square errors of the proposed estimators have been derived. The study on the cost of the survey under the proposed estimators has been discussed. An empirical study has also been carried out in the support of theoretical study.
