We introduce a new method for ranked set sampling with multiple criteria. The method relaxes the restriction of selecting just one individual variable from each ranked set. Under the new method for ranking, units are ranked in sets based on linear extensions in partially order set theory with considering all variables simultaneously. Results willbe evaluated by a relatively extensive simulation...

Abstract Fatal Shock, competing risks and stress models are utilized in reliability survival analysis to characterize various application types. In this context, paper aimed introduce a new class of bivariate distribution based on the Marshall–Olkin type. The proposed termed as Bivariate Extended Chen (BEC) so that marginals have distribution. Some properties derived explained. BEC parameters e...

AMS subject classifications: 62E15 60E05 Keywords: Bivariate exponential distributions Bivariate chi-square distributions Correlated quadratic forms a b s t r a c t We introduce a class of absolutely continuous bivariate exponential distributions, generated from quadratic forms of standard multivariate normal variates. This class is quite flexible and tractable, since it is regulated by two par...

A surface with boundary is randomly generated by gluing polygons along some of their sides. We show that its genus and number components asymptotically follow a bivariate normal distribution.

Bivariate semi-logistic and Marshall-Olkin bivariate semi-logistic distributions are introduced. Some properties of these distributions are studied. First order autoregressive processes with bivariate semi-logistic and Marshall-Olkin bivariate semi-logistic distributions as marginals are introduced and studied.
