Dear Maarten,
thnks a lot for your kind reply and for pointing out the feasibiliy of
Bonferroni correection for tests involving dichotomous variables.
BTW, have you got any reference about that?
Thanks a lot again and enjoy your W-E.
Kind Regards,
Carlo

Bonferroni like adjustements for multiple testing apply for any test,
including tests involving dichotomous variables. Some tools for
implementing these tests are available through the undocumented
-_mtest- command, see -help _mtest- (for those who are surprised that
an undocumented command has an helpfile, see -help undocumented-).
Hope this helps,
Maarten
