Abstract : In the present paper, we propose a generalized class of double sampling ratio cum dual to ratio estimator in two cases in presence of non-response to estimate the population mean of the study variable y . The bias and mean square error insert ignore into journalissuearticles values(MSE); of the proposed estimator has been obtained for both the cases. The asymptotically optimum estimator insert ignore into journalissuearticles values(AOE); in this class has also been obtained along with its bias and MSE. Comparisons have been made with the existing similar estimators theoretically and numerically to demonstrate the superiority of the proposed estimator.
