Sd. Term of Trade looks fine

Hallo Everyone

Can someone have a look at figure PriorPost3-eps-converted-to.pdf (45.1 KB)

Data is very informative for these estimated parameter
But it is fine for the case of the parameter

Blockquote Sd. Term of Trade

Thank you so much

The posterior is bimodal. That is very unusual. Are you sure the MCMC has converged?
