New class of bivariate gompertz distributions and its mixture

A new class of bivariate Gompertz distributions is presented in this paper. The model introduced here is of Marshall-Olkin type. The used procedure is based on a latent random variable with exponential distribution. A mixture of the suggested bivariate distributions is also derived. The obtained results in this paper generalize those of Marshall- Olkin bivariate exponential distribution and other present in the literature
