variance decomposition - mode/mean?

Dear all,
I am computing the conditional variance decomposition, using the command conditional_variance_decomposition in stochsimul, Dynare version 4.2.1.
Does Dynare compute it at the mode or mean of the posterior distribution?

Thanks in advance,
Lara

If you are doing stoch_simul, then you are using a calibrated model, not an estimated model. So I don't understand your question.

Best,

Dear Sebastian,
I have estimated the model and then used the command stoch_simul.
Thanks,

Lara

Dear Lara,

If you just estimated the mode of the posterior distribution, the variance decomposition is computed at the mode. If you run an MCMC the decomposition is done at the postrior mean (by default).

Best, Stéphane.
