RATIO-CUM-PRODUCT ESTIMATOR OF POPULATION MEAN IN SYSTEMATIC SAMPLING USING KNOWN PARAMETERS OF AUXILIARY VARIATES
In this paper, a ratio-cum-product estimator of population mean in systematic sampling has been proposed using Kadilar and Cingi (2006) estimator. The bias and mean squared error of the proposed estimator has been obtained under large sample approximation. The proposed estimator has been compared with simple mean estimator, usual ratio and product estimators in systematic sampling given by Swain (1964) and Shukla (1971) respectively. An empirical study has been carried out to demonstrate the performance of the proposed estimator.
