st: Streg (gamma): discontinuous region encountered

Hi --
I am trying to fit a Gamma model to determine which distribution to
use in streg. The following happens:
Fitting full model:
Iteration 0: log pseudolikelihood = -139.27247
Iteration 1: log pseudolikelihood = -133.40312 (not concave)
Iteration 2: log pseudolikelihood = -130.07612 (not concave)
Iteration 3: log pseudolikelihood = -129.51053 (not concave)
Iteration 4: log pseudolikelihood = -129.43679 (not concave)
Iteration 5: log pseudolikelihood = -129.37384
cannot compute an improvement -- discontinuous region encountered
Does anyone know what might be going on? Or if there is some other way
to do this?
thanks,
Jana
