NAN in the SKEWNESS and KURTOSIS moments

Hi,

I am new to Dynare and have a question regarding the 2nd-order stochastic simulation… The models runs okay, the steady state is solved, the rank condition is verified, but some of the variables have NAN in their skewness and kurtosis. What might have caused the problem? Please let me know if you need to see the code. Thank you very much! :stuck_out_tongue:

Something looks odd. Why are the standard deviations all 0? Please provide the mod-file.

I have made a mistake. Now it works. Thanks :slight_smile:
