I have a probability distribution of the form [tex]\sum_{i=0}^n f(n,x,y)[/tex]. There is no closed form expression for it. I need to know if there is any method that I can use to estimate the parameters {(adsbygoogle = window.adsbygoogle || []).push({}); n, x, y} given some data from the above distribution.

I've tried a maximum likelihood approach, but I'm having trouble getting the derivative with respect ton. Is it possible to get this derivative, and use a maximum likelihood approch to estimaten
