How to calculate the MH ratio in a birth-death Reversible Jump MCMC?

I know the formula and think I understand it, but I must be doing something wrong. Assume $J\sim po(\lambda)$ and $X_J=(U_1, \dots, U_J)$ and $U_i\sim U(0,w)$. Then I want to sample from the ...

A question about the choice and interpretation of the jumping distribution in Metropolis-Hastings algorithm

In order to implement the MH algorithm you need a proposal density or jumping distribution $q(⋅|⋅)$, from which it is easy to sample. If you want to sample from a distribution $f(⋅)$, the MH algorithm ...

Gibbs sampling with mixed prior using a Metropolis-Hastings step

My questions are about a sampling procedure for fitting a Bayesian hierarchical model where one of the priors is a mixture distribution of discrete and continuous parts. The model is not my own but I ...
