I've estimated the differences between a3b3 and all other combinations of levels.
However, I am interested in knowing whether a3b3 differs from all other combinations of levels combined. How can I do this in SPSS? Do I sum or average over all the other contrasts and test the difference between a3b3 and this sum/average? I tried this but it doesn't seem to work.
Should I be doing something different?
Any thoughts greatly appreciated.
