MCMC MH move proposal

[kai1991s]

Regarding the class "mcee.moves.MHMove(proposal_function, ndim=None)", I'm willing to use the MHMove for my problem but I need help in defining the proposal function. Is there a toy example from which I could learn the details?

I'm in the same boat. Is there a basic working example for this?

There isn't a worked example anywhere, but I'd recommend checking out the GaussianMove source code because it should give you an idea of how it's all supposed to work: https://github.com/dfm/emcee/blob/main/src/emcee/moves/gaussian.py

If there is no basic working example then has this method been tested?

[dfm]

Yes, it is tested.

[crhea93]

Is it possible to see the code that was used to test it?

This is fantastic! Thank you very much for taking the time to respond to these messages :) I'll work on getting a small working example to post here for others who may run into the same issue.
