Comparing the actual data with the simulated data of the model after completing Bayesian estimation

hello everyone
How to compare the actual data with the simulated data of the model after completing Bayesian estimation? Where should the actual data results be viewed? For example, I want to compare the covariance and correlation coefficients between variables.
Thank you for your answer!

Dynare does only provide the moments for the model. For the data, you would have to compute them yourself.

Thank you Professor! It turned out that I had misunderstood the meaning expressed in the paper before.
