Thanks to Kit Baum an update of the -betafit- package is now available
from SSC. To install it type in Stata -ssc install betafit, replace-.

betafit fits a two-parameter beta distribution, optionally as
dependent on covariates. The beta distribution is a flexible
distribution for modeling a variable bounded between 0 and 1, for
example a proportion. -betafit- is a joint project by me, Nick Cox and
Stephen Jenkins.

Michael Smithson has found a bug in the prediction function for
Pearson residuals. This update fixes that bug.
