Improved ratio estimators of population mean using transformed variable in double sampling

Abstract

Transformation techniques can be useful for improving the efficiency of the estimators. New ratio estimators for population mean using both the transformed auxiliary variable and the transformed study variable in double sampling have been proposed.  To see how the proposed estimators perform, a simulation study had been conducted in which a percent relative efficiency was used to compare the proposed estimators with some existing estimators. The results showed that the proposed estimators were more efficient than the existing estimators.
