Dual Use of Auxiliary Information for Estimating the Finite Population Mean under the Stratified Random Sampling Scheme
In this paper, we proposed an improved family of estimators for finite population mean under stratified random sampling, which needed a helping variable on the sample mean and rank of the auxiliary variable. The expression of the bias and mean square error of the proposed and existing estimators are...
