I'm trying to find the joint distribution of two independent identical gammas, say X~gamma(a,b) and Y~gamma(a,b). Is there any quick way to find it? Since they're independent? I know the joint will be the product of the marginals. Will the marginals just be the pdf of X and Y? If I'm not being clear, im asking if I can just multiply two gammas?
