Hello, I am trying to quantitatively assess my simulated DSGE model in fitting key macroeconomic statistics. I have a few questions:

Is it correct to compare the standard deviation of the cyclical component of key macro variables in the data with the standard deviation that I see under “Moments of simulated variables” after running the code, to say something about the fitting properties of the model?

How do you assess whether these standard deviations are “close enough”?

Do you have any clue of why the volatility of investment that I osberve under “Moments of simulated variables” is very small, whreas it is generally the most volatilile component of GDP? Which parameters, generally speaking, might affect this in a standard DSGE model?
Thank you!
