Abstract: For estimating the ratio of two population means, simple linear transformations using the known coefficient of skewness, coefficient of kurtosis and standard deviation of the auxiliary variable have been considered. The suggested transformations provide efficient ratio estimators than conventional and other ratio type estimators. Results are supported with numerical illustrations.

Keywords: Ratio, standard deviation, coefficient of skewness, coefficient of kurtosis, bias, mean square error
