Is there is a similar function to calculate the numerical value of the density of a given
multivariable distribution?
I have a function of a distribution H(x1, ...,xn) (not one of the known distributions),
i.e. I can calculate a value of H for any (x1..., xn) . And I want to calculate h(x1...,xn) for any (x1...,xn) BUT I don't know the analytical
expression of the density H.
