Obtain the IRF at zero period

Dear friends,

I want to obtain IRF of including zero period in response to stochastic volatility. Is it equal to stochastic steady state? How to obtain it?

I want to try it by this command,
oo_.stochastic_steady_state(var,:).

Is it right? Thank you in advance.

Best,

That will not work. What exactly do you want to do? I guess you are talking about higher order perturbation. In that case you need to tell us at which point you want to start the IRFs

Right. Thank you to your kind reply. Sorry that I might not understand your advice quite well. I want to start IRF at zero period from stochastic steady state.

Have a look at https://github.com/JohannesPfeifer/DSGE_mod/tree/master/Basu_Bundick_2017
There the IRFs are computed from the stochastic steady state and the letter is explicitly computed.
