A New Bivariate Distribution with Generalized Gompertz Marginals

E. A. El-Sherpieny, S. A. Ibrahim, Radwan E. Bedar


In this paper, we introduce a new bivariate generalized Gompertz distribution, it is of Marshall-Olkin type. Some properties of the distribution are studied, as bivariate moment generating function, marginal moment generating function and conditional distribution. Parameters estimators using the maximum likelihood method are obtained. A numerical illustration is used to obtain maximum likelihood estimators (MLEs) and we study the behavior of the estimators numerically.
