An improved estimation of parameters of Morgenstern type bivariate logistic distribution using ranked set sampling

Abstract

In this paper we have suggested some improved estimator of parameters of Morgenstern type bivariate logistic distribution (MTBLD) using ranked set sampling. We have shown the superiority of the proposed estimators over Chacko and Thomas (2009) estimators.
