AN ALTERNATIVE RATIO-CUM-PRODUCT ESTIMATOR OF POPULATION MEAN USING A COEFFICIENT OF KURTOSIS FOR TWO AUXILIARY VARIATES

An alternative ratio-cum-product estimator of population mean using the coefficient of kurtosis for two auxiliary variates has been proposed. The proposed estimator has been compared with a simple mean estimator, the usual ratio estimator, a product estimator, and estimators proposed by Singh (1967) and Singh et al. (2004). An empirical study is also carried out in support of the theoretical findings
