Hi!
We are getting a "new" error message we have never seen before: "Error - Unrecognized procedure specified: Model"
We are trying to run a multistate model with 4 states, 12 groups (cohorts) and 18 occasions. There are a lot of "initial" parameters but we are constraining the model substantially (> 4000 "initial" parameters but the design matrix has only 104 columns and we also use the PIMs to set some parameters equal; ~ 2245 separate parameters). There are a lot of permanent transitions and individuals never go back to their initial state. Many parameters are not state-specific.
We looked at the "tmp" file created by MARK when we start running the model: everything seems fine....
Does anybody know what may be happening and how to fix the problem?
Thank you in advance
Emmanuelle
