All estimators are biased estimator, then the mean square errors are determined. Furthermore, the mean square errors of each estimators are compared for showing which one is the efficient estimator. An numerical example is given to explain the problem discussed.otherratio estimatorsimple random samplingmediancoefficient of kurtosis and mean square errorOther
