Hello Johannes,
Referring to one of your old notes as above. I tried Nonlinear moving average method of Alexander Meyer-Gohde. So, there is method is approximation around the risky steady state right?
Using their add in “Nonlinear_MA 1.0.8.” for dynare at order 3 I found that It produced very similar second moments as when I do it with dynare with built in pruning. I am wondering why it is? Why there is no difference between these.
