DUAL TO RATIO-CUM-PRODUCT ESTIMATOR USING KNOWN PARAMETERS OF AUXILIARY VARIABLES
Keywords:
Dual, Ratio-cum-product, Bias, Mean Squared Error.Abstract
This paper deals with the dual to ratio-cum-product estimator for population mean using known parameters of auxiliary variables. In this paper, dual to ratio-cum-product estimator of Singh and Tailor (2005) has been suggested. The Bias and mean squared error expressions have also been obtained up to the first degree of approximation. Suggested estimator has been compared theoretically as well as empirically.
