Fitting the lclogitml command in Stata

[Fifamin Quenum]

Dear all,
I am facing an error message, while running the lclogitml command in STATA/ IC11.2. Actually, in the first instance, I used the lclogit command as recommended by Pacifico and Yoo (2012) to cluster pineapple consumers into 4 segments. Here is the command I used:

. lclogit choixpro prix notgout lnju, group(numfich) id(numfich) nclasses(4) membership(agpr agtr rich urbain disdom) seed(1234567890)

Then, in order to get class-specific inference, I used the lclogitml command as follows:

. lclogitml, iter(5) switch nopost

However, I got the following error message:
-gllamm- is initializing. This process may take a few minutes.
(error occurred in ML computation)
(use trace option and check correctness of initial model)
Can someone help me to understand why I am having this error message and how I could fix it?
Thank you very much

Yes, I'm facing a same problem. Can anyone have an idea to handle it?

This is no easier to answer than the previous question. Advice was given through the program. Did you follow it?

(error occurred in ML computation)
(use trace option and check correctness of initial model)

Can you get a simpler version of the model to work?

I attach the junk file which recorded all the model estimation process. Please examine it and tell me cause of the problem. Thank you!

I don't use these models, so wading through 40,000 odd lines doesn't appeal personally. Someone else may be tempted.
