Method of estimation in the presence of non-response and measurement errors simultaneously

The present paper discusses the problem of estimating the finite population mean of study variable in simple random sampling in the presence of non response and response error together. The estimators in this article use auxiliary information to improve efficiency and we suppose that non response and measurement error are present in both the study and auxiliary variables. A class of estimators has been proposed and its properties are studied in the simultaneous presence of non-response and response errors. It has been shown that proposed class of estimators is more efficient than the usual unbiased estimator, ratio and product estimators under non-response and response error together. In addition, a numerical study is carried out to compare the performance of the proposed class of estimators over others.
