I specified the first two moments. Solving the expressions for them for the shape and scale parameter, you get for the scale a q0 and for the shape 1/a.
By the way, this is all frequentist statistics. There is nothing Bayesian in here.

Thnx!! Sorry I was misconfused but marginalization and conditional probabilities make me think of Bayes
