Consider the following data: input var group 1 0 2 0 3 0 4 0 4 0 4 0 4 0 4 1 4 1 4 1 4 1 5 1 6 1 7 1 end

What we get now depends critically on what we ask for:

Wilcoxon rank sum test : Prob > |z| = 0.0196

Ordered logit regression with group as a predictor : P = 0.997 'Harrell's C' (as calculated by -somersd-) : .76, P < 0.001
