I need to simulate bivariate beta distribution, BIBETA(6,20,2) in r. I am looking for a package/ code that would generate bivariate beta distribution. I couldn't find the r function for this distribution.

Is anyone know which r function can be used for this simulation?

This is not a standard distribution. How is it defined? – Stéphane Laurent Oct 03 '18 at 13:24
Let BIBETA(a,b,c), then f(x,y) = 1/Beta(a, b, c) * {(x^((b-1)) * (1-x)^(a+b-1) * y^((c-1)) * (1-y)^(a+c-1))/(1-xy)^(a+b+c)} – score324 Oct 03 '18 at 13:31
Is there a probabilisitc representation? – Stéphane Laurent Oct 04 '18 at 10:07
Ok I have found one. See page 2 of [this article](https://arxiv.org/pdf/1406.5881.pdf). It's easy to simulate from three Gamma distributions. – Stéphane Laurent Oct 04 '18 at 10:13
@StéphaneLaurent Ok thank you – score324 Oct 04 '18 at 13:13
