Chris - Do you mean CI's for the mean, for both parameters simultaneously
or for percentage points?
Here's a reference that may be useful.

Is anyone aware of a STATA function to calculate confidence intervals for
a sample drawn from a Beta distribution?  I have applied findit, search,
and help, but no luck.

Thanks in advance.
