چکیده
|
In this paper, we obtain several estimators of a scale parameter
of Morgenstern type bivariate uniform distribution (MTBUD) based on the
observations made on the units of the ranked set sampling regarding the
study variable Y which is correlated with the auxiliary variable X, when
(X, Y ) follows a MTBUD. Efficiency comparisons among these estimators
are also made in this work. Finally, we illustrate the methods developed by
using a real data set.
