A Generalized Double Sampling Estimator of Population Mean Using Variable and Attribute Both

Peeyush Misra, R. Karan Singh

Abstract :

For double sampling procedure, the problem of estimating population mean by using auxiliary information in the form of attribute and variable both is considered. A generalized class of estimator is proposed and the bias and mean square error are obtained. It is shown that the proposed generalized class of estimator is superior to some of the previously studied estimators under the minimum mean square error criterion.
