Almost unbiased estimators for population mean in the presence of non-response and measurement error

In this paper, we have proposed three classes of almost unbiased estimators for population mean under simultaneous presence of measurement and non-response error. Asymptotic properties such as Bias and MSE for the proposed classes of estimators are obtained. Numerical illustration in support of theoretical results is also given on two real data sets and a simulated data set using R. Results indicate the superiority of proposed classes of estimators over existing estimators.
