# Math Help - Metropolis-Hastings/Objective Prior

1. ## Metropolis-Hastings/Objective Prior

Hi there,

I am doing some work on Bayesian Statistics and I need to simulate observations from a posterior using the Metropolis-Hastings method.

I am choosing an objective prior α^(-3/2)* β^(-1/2)
and my f(x; α, β) is a gamma distribution.

How can I work out the proposal density to use in the algorithm?
