Recently, Rodríguez-Lallena and´Ubeda-Flores [8] have introduced a class of bivariate copulas which generalizes some known families such as the Farlie-Gumbel-Morgenstern distributions. In this paper we present multivariate generalizations of this class studying symmetry and dependence concepts, measuring the dependence among the components of each class,(More)
In this paper we studied a three-parameter absolutely continuous bivariate distribution whose marginals are generalized exponential distributions. The proposed three-parameter bivariate distribution can be used quite effectively as an alternative to the Block and Basu bivariate exponential distribution. The joint probability density function, the joint(More)
Let be independent random variables with having half-logistic distribution with the scale parameter , for. Let be a random sample of size from a half-logistic distribution with the common scale parameter. The purpose of this paper is to study stochastic comparisons including usual stochastic ordering, hazard rate ordering and the dispersive ordering between(More)
