- Abstract
- Bivariate gamma distribution (BGD) can be used in hydrology, stochastic modeling and reliability theory. We derive the Laplace Stieltjes transform of the distribution of max{Y-1, Y-2} when a random vector (Y-1, Y-2) follows Kibble's BGD with integral shape parameter. This is achieved by showing that max{Y-1, Y-2} has the same distribution as the first passage time of a continuous time Markov process. (C) 2017 Elsevier B.V. All rights reserved.
