A General Class of Estimators in Presence of Non-response and Measurement error under Two-Phase Successive Sampling

In this paper, we consider a general class of estimators for estimating the population mean in twophase successive sampling in the presence of non-response and measurement errors. The expression of the biases and mean squared errors (MSE's) have been derived under the first degree of approximation. To check the performance, the proposed estimators are compared with the estimators under the complete response situation. A simulation study was carried out to evaluate the results. On the basis of the available results, appropriate recommendations have been made to the researchers.
