Nick-
Without having seen the code for -betafit- I can make a very educated guess
that mine is the most crude. Does -betafit- allow expreesion of both
parameters (or better, their log transforms) by linear combinations of
covariates?

One possibility already on SSC is -betafit-
(by Stephen Jenkins and myself). I have not
seen Al's code, so I am not sure who wins
on crudity.
Also -pbeta-, -qbeta- for some associated graphics.
