-ml- is a program that tries to find the maximum of a function. It is
what Stata uses to find the maximum of the likelihood function. If
that maximum is hard to find that subtle changes to the algorithm can
make a big difference in whether or not that maximum is found.
Generally, I would be suspicious of any results where such subtleties
matter, but there are exceptions. Since you did not give us the
information I asked for I cannot be more specific than that.
