Hello,

I am using the scheffe option to compare means of a continuous variable 
(drink) for several groups (year in college):

oneway drink year, tabulate scheffe

This option is great. It produces a table showing means and P-values for all 
combinaison of groups.


What would be the correct command to compare a dichotomic variable (say 
heavy drinker vs occasional drinker) for the same groups (year in college) ? 
I need to get frequencies and chi2 contributions in a table, for every 
possible group comparisons.

Thank you,

Claude
