A class of exponential chain ratio-product type estimators with two auxiliary variables under double sampling scheme


In this paper an exponential chain ratio-product-type estimators in double sampling has been developed using information on two supplementary characters for estimating the finite population mean. The optimum property of the suggested strategy has been studied. Comparisons of the efficiency of the proposed estimator under the optimality condition with other estimators have been presented through empirical investigations.
