Modified generalized chain ratio in regression type estimator for population mean using two phase sampling in the presence of non-response has been proposed and their properties have been studied. Relative efficiency of the proposed estimator is obtained in the case of fixed first phase sample, second phase sample and sub sample fraction. A comparison of the proposed estimator has been carried out with the relevant estimators. The performances of the proposed estimator in comparison to the relevant estimators have been made with the help of an empirical study.
