   You are right, I mean two-parameter item response model. I have tried
   gllamm, but it is very slow and not suitable for large datasets. I am
   wondering if there is another ado file in Stata.

   Thanks

   There is no such thing as a 2-parameter Rasch model.
   By definition, Rasch is a 1-parameter model.
