AN ALTERNATIVE ESTIMATION OF THE SCALE PARAMETER FOR MORGENSTERN TYPE BIVARIATE LOG-LOGISTIC DISTRIBUTION USING RANKED SET SAMPLING
Abstract
In this paper we have suggested some improved estimators of a scale parameter of Morgenstern type bivariate log-logistic distribution (MTBLLD) envisaged by Lesitha and Thomas (2012), based on the observations made on the units of ranked set sampling regarding the study variable Y which is correlated with the auxiliary variable X , where X ,Y follows a MTBLLD. Numerical illustration is given in support of the present study. AMS
