A Class of Ratio cum Dual to Ratio Estimator of Finite Population Mean in Presence of Non-Response

W. Warseen Chanu, Bhupendra Kumar Singh

Abstract


In this paper, we suggest an estimator for the population mean of the variable of interest y in the presence of non-response in two situations. We obtain expressions for the bias, mean square error and optimum value of 'alfa' for the suggested estimator. This study is supported by the theoretical and empirical result to show the performance of the proposed estimator over usual unbiased estimator and other existing estimators.

Keywords


Estimator, Non-response, Bias, Mean square error, Optimum value.
