"Bivariate models involving independent gamma distributed components "
Streszczenie: Several multivariate models involving independent gamma distributed components (three of which are new) are described. The flexible bi- variate beta(2) model introduced by Arnold and Ng (2011) provides the template for the other models. It involved ratios of sums of inde- pendent gamma variables. The other models involve differences, sums, products and minima rather than ratios.
