Estimation of Population Mean using Supplementary Information in the Presence of Non-response

Abstract

Non-Response is the biggest problem of survey sampling, and it decreases the reliability of the estimators. To overcome this problem, we proposed a more efficient exponentialtype estimator using two supplementary information’s under the conditions of either nonresponse in both study and auxiliary variables or just in the in-study variable. In addition, some conditions are obtained under both situations which showed that our proposed estimator performs more efficiently. Finally, we use some real-life datasets to prove that the proposed estimator performs more accurately in both situations as compared to the existing estimators.
