Using S-Plus 4.5, what is the most efficient numerical method for
computing (in 1000 points, say) the density or probability function of X
+ Y, where X and Y are random variables whose joint density or
probability function is given?

Is there a special method when X and Y are independent?

Please tell me if You know of a good reference about such questions.

Thanks in advance
