The RATS Software Forum

Hello:
I'm working with rats and cats of my university.

When I try to impose restriction on Beta. whatever restriction I Impose the program always crashes. it appears an error who says: the chosen normalization invalidates calculation of the "standard errors" for beta. The same problem when I test zero-restriction on beta.

I Changed the normalization but the program crashes. Also in the output appears the following:

It would be hard to tell anything without knowing more about the model. You would have to send us the data set, the @CATS instruction and tell us what rank you've set and which restrictions you're trying to impose. In general, the restrictions on beta works, so there must be something special about your model.
