Yes, it's exactly this command. I already read the description of the
sintax, but there is not an help file.So I really don't know how to
find some help. Maybe someone could help me to know if it's possible
to test for dominance for a concentration curve with categorical
variable on x-axis and 45 line because I have the feeling that one
problem in testing dominance with categorical variables is that I have
only 5 point estimates. What you suggest to do?

Many thanks

Vincenzo
