Hi Freesurfer Experts,I have tried to alter wiki example FSGD table into my
analyses these days, according to your advice, but there are still some
problems. Supposed there are 6 groups (maleclass1, maleclass2, maleclass3,
femaleclass1, femaleclass2, femaleclass3) and 2 Variables (age, education) in
my study, I have already known that:male.class1-vs-class2.mtx 1 -1 0 0 0 0
0 0 0 0 0 0 0 0 0 0 0 0female. class1-vs-class3.mtx 0 0 0 1 0 -1 0 0 0 0
0 0 0 0 0 0 0 0but I am not sure whether it is right for:male-female.mtx
[1 1 1 -1 -1 -1 0 0 0 0 0 0 0 0 0 0 0 0]/3 (Null Hypothesis: is there a
difference between Males and Females regressing out the effects of class, age,
and education?)class1-class2.mtx [1 -1 0 1 -1 0 0 0 0 0 0 0 0 0 0 0 0 0
]/2 (Null Hypothesis: is there a difference between class1 and class2
regressing out the effects of gender, age, and education?)class.diff.mtx +0.5
