guys
can u plz help me out in calculating the posterior distib of the gamma function of form :

p(lambda/alpha,beta) = (beta^alpha)*lambda^(alpha-1)*(e^(-beta*lamda)))/gamma(a)

lambda>0 mean=alpha/beta mode = (alpha-1)/beta ;alpha>0

the integration seems really tuff which makes me feel tht im going in the wrong direction.. can u guys help me out with this plz...

I have no idea what you mean by the distribution of the Gamma function. The Gamma function has a Dirac distribution (same as saying it is deterministic). If you mean the Gamma distribution (you equation kinda looks like it), you may want to read http://en.wikipedia.org/wiki/Gamma_distribution
I would kindly ask that you use LaTex when writing equations or using simple constant/variables like a,b,c,d,e... I can't decipher the equation.
