Hi, All,
I have a density function with 3 variables which is defined on some
irregular domain, and I want to get the marginal distribution of each
variable. Is there any function doing this?
A simple example is p(x,y,z)=x*y*z*I(xy>z). So each marginal distribution is
a function of the other two variables. My density form is very complicated,
so I cannot do it by hand. I was just wondering if there is any function in
R for this?
Thanks,
Cindy
