Prior Bayesian IRFs

Dynare Reference Manual says that ‘estimation’ command with ‘bayesian_irf’ option triggers the computation of the posterior distribution of IRFs. Does it is possible to compute IRFs based on the prior distributions specified in ‘estimated_params’ block? In other words, I am looking for a way to compute IRFs solely based on prior information of the model parameters.

That is a bit more complicated, but can be done with the prior_function-command. See

Thank you very much!
