Title: "The bivariate gamma distribution with Laplace transform $(1+as+bt+cst)^{-q}$: history, characterizations, estimation"

The above distributions -sometimes called the Kibble -Moran distributions- have
been used as a model of dependent positive random variables with few parameters.
We consider them here as exponential families, we review their characterizations
and we compare methods of estimations..
