RATIO AND PRODUCT TYPE EXPONENTIAL ESTIMATORS FOR POPULATION MEAN USING RANKED SET SAMPLING.

In this paper, we suggest an improved form of exponential ratio and product estimators using ranked set sampling (RSS) in order to estimate the population mean ... of study variate Y using auxiliary variate X. The mean-squared error (MSE) of the proposed class of estimators is obtained. To judge the merits of the suggested estimators over others a simulation study has been carried out.
