Hi, there: is there some functionality in dynare that I can check if the prior is good enough, say, not easy to run into unadmissable region by the DSGE model (indeterminacy of non-stable equilibrum)? I am running a model that the mean of prior is OK, since I can generate some reasaonabl IRFs, but the estimation step stops due to bad gradient.

Thanks in advance.
