Stas Kolenikov <> needs derivatives of a likelihood function
he is using with Stata's -ml- command:

Stas mentions 'scores' in his title and 'derivatives of the likelihood
function'.  If he wants the equation-level scores once -ml- has fit the
likelihood model, try

	. help ml score

However equation-level scores are not available to method 'lf' likelihood
evaluators while -ml- is running.
