Hi.

I solved and simulated an RBC model in non-linear form.Now,I want to compare simulated and real data moments( standard deviation).

My question is that I solved and simulated the model in a non-linear form but not log-linear.

When I want to compare the simulated moments with real data moments, can I use logarithm of GDP and logarithm of Consumption?

I seasonally adjusted my real data, then I transformed them to Logarithm for example LogGDP or LogCONSUMPTION, then I derived cycle with HP filter and then I compared the standard deviation of these variables with standard deviation of simulated data in Dynare.

I want to know that my work is right or not?

I ask this question,because my model is not Log-Linear,but when I compare the standard deviations of simulated and real data, I use logarithm of real data such as GDP,Consumption,Investment

Thank you so much.
