I just have a quick and simple question about stoch_simul.
I notice that some of the IRFs do not output.
What I mean by that is
when I type in
stoch_simul(irf=20, irf_shocks = (xi)) i_r i_d i_l Y z;
and run this code, I get a plot for i_r, i_d, i_l and Y but not z.
Is there a reason for why IRF for z do not output? If so, how do I fix the issue?
