A GENERAL PROCEDURE FOR ESTIMATING FINITE POPULATION MEAN USING RANKED SET SAMPLING

Abstract

In this article, we have suggested general class of estimators of the finite population mean using an auxiliary variable that is correlated with the variable of interest using ranked set sampling (RSS) method. We also obtained the biases and mean squared errors (MSEs) of various suggested estimators. We have compared newly suggested generalised ratio-cum-product type estimators to others existing estimators and shows that our suggested estimators are better than other existing estimators. This paper also provides the correct expressions of MSE of the estimators due to Mehta and Mandowara (2012, 2016) and Mandowara and Mehta (2013).
