They are listed if I evaluate nlm["Properties"] (nlm being the name of fitted model), but when I evaluate them directly (e.g. nlm["ParameterTable"] ) I get "Missing[]" as a response. I can still access all the other properties.

Hello Steven,

I read your problem now, I have the same problem. How did you solve it?

Thank you very much!
