I am a beginner in dynare. I encountered some issues while exploring the functionalities of dynare. I attempted to find answers through the user manual but was unsuccessful. The original model is from Prof. Pfeifer’s Github, and I am using dynare version 5.3.
(1) I only retained the prior settings for the standard deviation of shocks under
estimated_params. I noticed that modifying the prior distribution,
mh_jscale for the standard deviation of shocks affects the estimation results, but does not impact out-of-sample forecasting results. Is the situaiton reasonable? Why doesn’t it affect out-of-sample forecasting results? Does this imply that setting different shocks for the same model doesn’t affect out-of-sample forecasting results, meaning out-of-sample forecasting results only depend on the setting of endogenous variables in the model?

(2) By removing the
estimated_params command and using
calib_smoother, I am still able to obtain out-of-sample forecasting results, and they seem to be exactly the same as the results in question 1. Why is it possible to run the model using
calib_smoother instead of the
estimated_params command? Am I essentially instructing the
estimated_params command to perform only out-of-sample forecasting?

(3) Can the variable estimation results obtained after using the
calib_smoother command be used to assess the model’s fit to the data, such as comparing the standard deviation of the output from
calib_smoother command to the standard deviation of the data?
