Yes, that is correct. It is testing the null hypothesis A=B=C=D=E=F. That
hypothesis will be rejected if A is different from B-F, which is what you are
testing. The other contrasts are redundant (and would cause an error if you
added them to the contrast matrix)z

Hi,
I'm designing an analysis that will have 6 groups (two factors/three levels). I
was wondering if I could get some input regarding my contrast for the group
effect. Based on the group effect contrast under the FSGD examples for 3 groups
I've written a five line contrast file that compares group 1 against the other
5 groups.
1-1 0 0 0 0
1 0 -1 0 0 0
1 0 0 -1 0 0
1 0 0 0 -1 0
1 0 0 0 0 -1
Which from my understanding should cover the rest of the contrasts such as 2v5
3v6 and etc. Is my understanding of this correct?
