I have the following problem and I hope that someone here can enlighten me.
I am running the following analyses with the indicated post-hoc comparisons:
GLM agg1 agg2 agg3 BY sa
/WSFACTOR=Zeit 3 Polynomial
/EMMEANS=TABLES(sa*zeit) compare (zeit) adj (bonferoni)
The factor "Zeit" has three levels and with the compare (zeit) command above I am getting all comparsions (1.vs 2, 2 vs. 3. etc.). However, I need to test specifically one level (for example agg1) against another one (for example agg 2).
And I dod not know how to tell SPSS to do that.
Importantly, it is that I need to compare agg1 with agg2 on each level of sa seperately.
Additionally, I see the "significance" column in the "Pairwise comparison" table. This might be a hint, but I do not see a) the exat test statistic and b) degrees of freedom or the like, which I would need to properly report the results.
The multivariate table below, again, indicates the comparsion for all types of combinations of "Zeit".
I hope that this was clear enough, to grasp what the problem is. I am convince that this is not a statistical problem but more one of SPSS or - better - me and SPPS.
Thank you very much in advance!
