Analytic integration of profile likelihood vs marginal likelihood?

I have questions about 1. Method of analytic integration 2. Statistics (marginal vs profile)



I have an expression



$p(N|a,s,b) = frac{exp[(-as+b)](as+b)^N}{N!} * frac{exp(-gs)(gs)^A}{Gamma(A+1)}*frac{exp(-hb)(hb)^B}{Gamma(AB+1)}$



which I need to analytically integrate into



$p(N|a)$



First, I understand s, and b are separable so it's easy to integrate AS LONG AS
$frac{(as+b)^N}{N!}$ can be somehow separated.....



Is there a way to separate the $frac{(as+b)^N}{N!}$ so I can separate the s and b variable and analytically integrate?



Second, What are two different ways to



a. compute profile likelihood $p(N|a)$ by maximizing probability above



and



b. compute marginal likelihood $p(N|a)$ by integrating above?



Thank you for your help for this newbie!
