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{Y₁,Y₂} when a random vector (Y₁,Y₂) follows Kibble's BGD with integral shape parameter. This is achieved by showing that max{Y₁,Y₂} has the same distribution as the first passage time of a continuous time Markov process.
