# Suggestion for additional preprocessing check

Hi,

by accident, I made a copy and paste mistake in the estimated_params section. I had included one parameter, a standard deviation of a shock, twice. Dynare then estimated the model without any error message and gave me two different values for the estimated standard deviation at the posterior mode. I have no idea what Dynare did internally, but obviously having two values simultaneously makes no sense.
Hence, I would suggest to add an additional check in the preprocessing if the parameters to be estimated are uniquely specified.

Best regards,

Johannes

Thanks for the suggestion. We will add it to a next release.

Best
