Hi
I'm interesting in using Randomise to run F-test to investigate the group difference between condition a, b, c. We'd like to know if there's a difference between a vs b OR a vs c OR b vs c.
Now I'm thinking to use the contrast
[1 -1 0]
[1 0 -1]
[0 1 -1]
and only the first two contrast are selected for 1 F-test.
Is my design above corrected? If yes, then what the design file looks like if instead we're asking if there's a difference between a vs b AND a vs c AND b vs c?
Thank you!
