چکیده
|
In this paper,we obtain several estimators of a scale parameter of morgenstern type bivariate rayleigh distribution based on the observations made on the units of the ranked set sampling regarding the study variable which is correlated with the auxiliary variable. we also compare the efficiency of these estimators. finally,we illustrate the methods developed by using a real data set.
