Hmm, I could be talking out of my butt, here. The last time I looked
at something like this was years ago, and my problem was just
generating random numbers, not trying to derive density functions. I
was looking at the NORTA (NORmal To Anything) method. It might be
possible to derive a method for estimating a joint density using a
What information do you have? Just the marginal densities? Can you
describe your problem at a higher level?
