Dear SPM community,
I have a question about conjunction analysis.
I have two groups (G1 and G2) and two conditions (A and B).
I did two conjunction analyses between A and B, one for each group. What
I’m interested in is to compare the two conjunctions.
Would be the comparison [A(G1) – A(G2)] ∩ [B(G1) – B(G2)] correct?
What I want to know is the result of [A(G1) ∩ B(G1)] vs [A(G2) ∩ B(G2)].
Any hint would be appreciated!
Thanks!
Best,
Federica
