You could also write your own ML routine using a beta distribution. Actually
I am surprised that Stata doesn't already have some sort of
"beta-regression" built into it. Actually, I already have a crude version of
such a program if anyone wants it.

You would need to use -glm- set of routines with -family(binomial)-.
If you also want all of the residual diagnostic tools provided by the
-regress-, you can back-transform your data by taking inverse logit or
probit links ( ln(y/(1-y)) and invnorm(y), respectively), although I
am not quite sure there is a solid statistical foundation for doing
