Hi everyone, I’m happy to announce that VineCopulas.jl is now registered in the Julia General registry. VineCopulas.jl is a pure-Julia package for explicit vine copula models, built on top of Copulas.jl. The current re…

An example of fitting a copula using the Copulas.jl package is given as the following in the docs: MyCop = SurvivalCopula{4,ClaytonCopula,(2,4)} MyMargs = Tuple{LogNormal,Pareto,Gamma,Normal} MyD = SklarDist{MyCop, MyMa…

I’m running into domain issues when trying to compute the convolution of two random variables where their joint distribution is defined by a copula. By convolution I mean: f\_{Z}(z) = \\int\_{-\\inf}^{\\inf} f\_{XY}(x,z-x)dx…

Hi all, I am a big fan of both libraries, but when I try to include copulas in probabilistic (Turing) models, I often get errors related to quantities being out of bounds. I have included a simple example below. The be…
