On Efficient Estimation of the Population Mean under Stratified Ranked Set Sampling
This paper considers some efficient combined and separate classes of estimators of the population mean in the presence of bivariate auxiliary information under stratified ranked set sampling. The mean square error MSE expressions of the proffered combined and separate classes of estimators are deriv...
