I am trying to undertand how to set up a 2x3 ANOVA, where I can see the effect of factor A, effect
of factor B, and the interaction between A and B.
I am reading the tutorial (slide titled 2-factors 2 - levels. I am having difficulty understanding it.
You have 8 inputs, one for each subject. I am guessing this would be a 1stlevel.feat directory
without repeated measures. These are your EVS
Group EV1 EV2 EV3 EV4
input 1 1 -1 -1 1 1
input 2 1 -1 -1 1 1
input 3 1 -1 1 1 1
input 4 1 -1 1 -1 1
input 5 1 1 -1 -1 1
input 6 1 1 -1 1 1
input 7 1 1 1 1 1
input 8 1 1 1 1 1
Where EV1 = Factor A
EV2 = Factor B
EV3 = Interaction between A and B
I am definately missing something here. For example, it looks to me like you are subtracting
subjects 1-4 from subjects 5-8 in EV1...
I think I may be mistaken about what the inputs are, and you don't specify.
