I have a model that I estimate well under Dynare 4.4.3 with intuitive posterior means and, most importantly, a definite posterior log data density. When I estimate exactly the same mod file, with the same data, with Dynare 4.5.0 to 4.6.4, I always obtain “Log data density is -Inf” while the estimated parameters and other results are roughly similar.
I read the major user-visible changes from the Release of Dynare 4.5.0 email (2017), but I cannot understand what provokes such a difference.
Does the Dynare team aware of this issue? Can I rely on Dynare 4.4.3 ?
Is there a way to retrieve a definite calculation of the posterior log data density with the last Dynare version?
May I use the last Dynare version (which is assumed to be more robust than the previous ones, right?) and use the log data density (Laplace approx, before MCMC-MH, which is definite) instead of the posterior log data density?
Thank you in advance for your help.
Thanks to all the Dynare team, you are doing a fantastic job!
