Hello Dynare community,

I’m currently working on a DSGE model simulation and facing challenges when attempting to plot the variance decomposition after the simulation. My issue is that the oo\_ structure does not generate the expected output for graphs.

I am using the following code for my simulation:

stoch\_simul(order=1, irf=30, periods=1000000, conditional\_variance\_decomposition=[1 2 5 10 50 10000]) yH yX yN yA gdp;

However, I am unable to find the conditional variance decomposition results in the oo\_ structure. It appears that the necessary fields for plotting the results are not being generated.

I have attached my full code for reference (please find the attachment). I am not sure where the issue lies. Any insights or suggestions would be greatly appreciated.

Thank you for your assistance!

Best,  
Yamoi

Conditional variance decompositions can only be computed based on theoretical moments. You need to drop the `periods` option.
