A Generalized Ratio in Regression Type Estimator for Population Mean Using Auxiliary Variables in the Presence of Non-Response

B.B. Khare, Habib Ur Rehman

Abstract


A generalized ratio in regression estimator for population mean using auxiliary characters has been proposed and its properties have been studied. A comparative study of the proposed estimator has been made with the relevant estimators. For optimum value of , the proposed estimator is found to be more efficient than the relevant estimators which is supported by the empirical study. A range for alpha has been obtained for which the proposed estimator is more efficient than relevant estimators.
