Bayesian IRF ML/Bayesian estimation

The mean of the the Bayesian IRFs is the mean of the distribution of the IRFs generated when parameters are drawn from the posterior distribution. When you run stoch_simul after MCMC, the parameters of the model are set to their mean value in the posterior distribution. But an IRF is a nonlinear function of the parameters, therefore the mean of the IRF is not identical to the IRF for the mean value of the parameters Best Michel
