Prior predictive check

Hi, I was wondering if there is an easy way to perform a prior predictive check (this is before estimation). In particular, whether I could get something like the bayesian_irf but with the prior distribution. I apopreciate any help

You can do this using the prior_function-command. I did this for a variance decomposition in

Thanks a lot. I am trying to use the GetOneDraw(‘prior’) function but is not working. is there any other option to get a draw from the prior?

What does

mean? What is the problem/error message? Can you provide the files?
