Posterior standard deviation

One of output resulting from DSGE-estimation is ‘oo_’ and as far as I know, this variable contains various estimated results.
My question is that whether ‘oo_.posterior_std’ includes standard deviations of MCMC-simulated draws.
One thing strange is that there is also ‘oo_posterior_variance’ and I was sure that I could get values in 'oo_.posterior_std’
after imposing square root on them. However, resulting values are little bit different.
Is there any one could explain these outputs?


This is an unfortunate inconsistency. The

field is set after mode-finding, i.e. it is the parameter standard deviation at the posterior mode.

field is set after the MCMC algorithm. That explains why they are not the same. We will fix this in future versions.
