Estimation of Parameters of Morgenstern type Bivariate Lindley Distribution by Ranked Set Sampling

Abstract

In this work, we have discussed the problem of estimation of the

parameters of Morgenstern type bivariate Lindley distribution (MTBLDD) us-

ing ranked set sampling. We have proposed two estimators, namely an unbiased

estimator based on the Stoke's ranked set sample and the best linear unbiased

estimator (BLUE) based on the Stoke's ranked set sample. The efficiencies of

the BLUE with respect to the unbiased estimator are also evaluated in this work.

Keywords

• Ranked set sampling,Best linear unbiased esti- mator,Morgenstern type bivariate Lindley distribution.
