Hello R-Team, I am trying to construct a Copula from a multivariate Gamma distribution with its marginals gamma-distributed. The multivariate Gamma should be able to contain a correlation coeficient or matrix. I have studied the book "Continuous Multivariate Distributions vol.I Models and applications" by Johnson & Kotz & Balakrishnan but what I constructed doesn't really look like a Copula. So my question is: Can such a Copula exist? And if yes, are ther R-packages which could help? Yours truly Peter
