credible set IRFs given priors

[bredemar]

Hey all,
in very general form my question is the following:
I want to estimate a model to test certain economic hypotheses. Before doing so I want to show that certain versions of the model, i.e. when I restrict certain parameters, are not able to capture the behaviour of some economic variables after some shock X. In particular I would like to show IRFs with credible sets given the priors to clarify that certain parameters drive the model's ability to accept or reject the hypothesis.
Is there an easy way to do this? Like a bayesian_IRF option in stoch_simul given the priors?
Thanks for any hints and suggestions

So you want to conduct a prior predictive check. The probably easiest way to do this is to use the unstable version/4.5 with the

Code: Select all

prior_function

command. It allows you to execute arbitrary exercises on draws from the prior distribution. See http://www.dynare.org/phpBB3/viewtopic.php?f=1&t=15246 and the manual. Get back to me when you need assistance.
