Derivation of Dirichlet distribution from gamma distributed variables
You said ...

"I just wanted to ask you whether you can explain to me what has happened to the Jacobian during the derivation of the dirichlet distribution from gamma distributed variables (in the proof you have removed in the article 'Dirichlet ditribution')? I think it's more or less the same proof as in Luc Devroyes book referenced in that article, but I don't understand this one either."


 * I didn't try to follow the supposed proof. But have you looked at Chapter 49 of "Continuous Multivariate Distributions" (Volume 1), by Kotz, Balakrishnan & Johnson ISBN 0-471-18387-3 ... which seems to be going through the same derivation in a different notation.
