Looks like -dbetafit- is choking on too large a variable list
somewhere. Can you sent me privately an example -- a do-file
and you your data, a random sample of your data, or fake data
-- where this error occurs? Than I'll try to fix -dbetafit-.
Though I and all other authors of -betafit- will be at the
UK Stata Users Meeting the next two days, so it may take a
couple of days before I get back to you.
In the mean time you can use -mfx- after -betafit- to get
marginal effects.
