RATIO-RATIO-TYPE EXPONENTIAL ESTIMATOR OF FINITE POPULATION MEAN IN DOUBLE SAMPLING FOR STRATIFICATION.

In this paper, we have suggested a ratio-ratio-type exponential estimator for finite population mean in double sampling for stratification (DSS). To the first order of approximation the bias and mean squared error of the suggested estimator are obtained and compared theoretically and numerically both with unbiased estimator, ratio and product-type estimator and ratio and product-type exponential estimators. An empirical analysis is also being performed in support of the study. [ABSTRACT FROM AUTHOR]
