Hello experts! I am working with a 2 (between subjects) x2 (within subjects) x3 (within subjects) project. I have added 2 GLFs to the model to look at sub-interactions. I am confused that the output buckets for these sub-interactions say Z next to their title in afni viewer, instead of F like the automatic F tests calculated and their corresponding buckets. My understanding is that the output buckets for the sub-interactions should be F statistics but seeing the Z in the bucket titles is making me question whether that is the case. The distribution of the sub-interactions are also positive only, which similarly makes me think they are F distributions. I would appreciate clarification on this! Thank you!
