Hello everyone,

I am wondering if there is a range for the mh_jscale parameter. Normally, I have to use small values in order to get an acceptance ratio of around 30%. Nevertheless, I am estimating a model in which I have to fix a mh_jscale of 10.

I know that the efficient variance of the MH random walk depends on the model I am estimating but is it not too high? is the MH going to reach the tails of the distribution?

Have I misunderstood some technical concepts or should I worry about some mistake in my model?

(I am considering two blocks and the ratios are close to each other)

Thank you in advance for any comment.
