oo_.mean from 3rd-order approximation?

The 1st and 2nd order approximation give
Code: Select all
oo_.mean

but 3rd order approximation doesn't. How to get the theoretical mean when I use 3rd order?

Most probably because you are requesting theoretical moments, which are not yet implemented at
Code: Select all
order=3

If you use the
Code: Select all
periods

option, the field will be there.

Dear Prof. Pfeifer,

Thank you for the answer.

I add the option "periods" as follows,
Code: Select all
stoch_simul(order = 3, periods=0, nograph, irf=0);       

following the Dynare manual, which says "If different from zero, empirical moments will be computed instead of theoretical moments."

However, I still couldn't find
Code: Select all
oo_.mean
Did I make a mistake using the "periods" option?

Your setting of
Code: Select all
periods=0

is NOT
different from zero

Oh I misread it. Thank you.
