Measurement equations for log-linearized modelse

Otherwise I cannot run the estimation. With an extended model which includes more parameters it seems to be necessary to also exclude more parameters from the estimated params command

I meant: what is the problem/error message you encountered that required you to fix parameters. Typically, that is only valid if there are identification problems.

Dear Professor Pfeifer,

the error message I get is:

Log data density [Laplace approximation] is NaN.

Error using chol […]

If I interpret correctly, the error message indicates that there is an identification problem.

That message in itself can have various reasons. More careful debugging is needed.

I see. Thank you very much for your help, Professor !
