Hi Douglas,

I am not obtaining the same pattern testing for Group A > Group B  (c=[1 -1]) and Group A < Group B (c=[-1 1]). That's why I am a bit confused.

Thank you very much! fab

    Hello,
    When comparing 2 groups I obtain negative sig.mgh values
    testing for Group A > Group B.
    Shouldn't I get positive values of sig.mgh when testing for
    Group A < Group B?

    Thank you.
    Best,
    fab
