Metropolis Hastings Stuck in Local maxima
I've been running the metropolis hastings algorithm to infer some parameters.
After running multiple chains, there are typically two places the chains get stuck in, one of which has a higher likelihoo …

MCMC - one chain behaving differently
I'm using an adaptive MCMC (metropolis-hastings) scheme to infer some parameters. I've run 7 chains, each starting from a random point.
6 of the chains vaguely converge to the same area, but one of t …

Discrete Proposal distribution MCMC
If you want to perform MCMC (Metropolis-Hastings) to infer discrete values, what are some proposal distributions you can use for this. I can't think of a way to extend the notion of a gaussian proposa …
