Now, we'll compute the proportion correct (as a proportion of values 1-3) for each variable:


   egen correct = max((y==1)*cnt), by(Var)
   egen nonmiss = sum(inlist(y,1,2,3)*cnt), by(Var)
   bys Var (y): replace cnt = correct[1] / nonmiss[1] if y == 5


Note for the record that the third line above may be replaced with the simpler


    replace cnt = correct / nonmiss if y == 5


(the original was left over from an initial approach which I then simplified).
