Dear Maarten,
thanks a lot for the correction.
I was thinking of the beta binomial conjugacy under the Bayesian framework.
But here the matter is different.
I do hope that everything is fine with you and hope to have the pleasant
chance to meet you again.
Kind Regards,
Carlo

This will create a random variable from a continuous
distribution (the beta distribution) whose values are bound
between 0 and 1. To create a binary variable you can type:
-gen A = runiform() < .5-. For more on this see:

uniform(). The Stata Journal, 7(3):434--435.

Hope this helps,
