suppose I have a dataset so that I use   proc tabulate  data = a ;    class a b ;    table a, b ; run ;   and I get          b a      0      1 0      2     4 1      3     1   what I want is margins on *both* sides and then percentages of the total on both margins: that is:           b a       0       1        all 0      20     40       60 1      30     10       40  all   50     50     100   I have a grim suspicion that this is not possible, but I would like to be proven wrong.   Bendix Carstensen Senior Statistician Steno DIabetes Center Copenhagen          ...
