Ratio-Cum-Product Type Estimator of Finite Population Mean in Case of Post Stratification

PP: 103-106
Rajesh Tailor, Hilal A. Lone, Rajiv Pandey, Manoj Kumar,
In this paper, a ratio-cum-product type estimator in case of post-stratification has been proposed. The bias and mean squared error of the proposed estimator are obtained up to the first degree of approximation. The mean squared error for the proposed estimator has been obtained and it has been shown that the proposed estimator is more efficient than the usual unbiased estimator and the estimators suggested by Ige and Tripathi [7]. Theoretical conditions are obtained under which the proposed estimator is more efficient than considered estimators. Finally, in order to find the merits of the proposed estimator an empirical study has been carried out.
