A parameter is not identified!

Hi Prof Pfeifer,
I hope you’re doing well,
The results of my model seem fine, except for a warning from the Identification test showing that one of my parameters is not identified. This is one of the main parameters, so I can’t fix it. Could you please help me find where the problem comes from? Thank you so much!

You are neglecting parameter dependence. There are parameters depending on lambda that should be model-local variables.
