# Impulse responses functions

Dear,
i have estimated a a new keynesian model with dynare . After the estimation (Matlab displayed the estimates parameters) i did not get the impulse responses function. How can i do to find them
Best regards

Dear Bamba,

if you have done Metropolis iterations, you should use the option bayesian_irf in the estimation command

if you have only computed the posterior mode, you should do stoch_simul to have the IRFs when the parameters are set at the posterior mode.

Dear Michel,
i have estimated the model with the maximum of likelihood methods, can i get theIRFs without using stoch_simul or it 's necessary to use stoch_simul;
best regards

If you have estimated with ML, you must use stoch_simul.

Kind regards

Michel

thank
i have already done it; i thought that it was possible to do it without using stoch_simul
