I need help with post hoc testing in repeated measures. I have 4 groups of mice.
Grp 1: +prog, +PRM, Grp 2: -prog, +PRM, Grp 3: -prog, -PRM, Grp 4 +prog, -PRM. The outcome is a continuous variable called LVDd. LVDd is measured at times 0 wk, 2 wk and 4 wk. Data is expressed as % change for 2 wk and 4 wk compared to 0 wk.
I need to know the difference between 2 and 4 wk in each group and the difference between groups at 2 and 4 wks. When I set it up I only get overall p values for prog and PRM and the interaction but no post hoc testing. Please help! Please make any directions very simple as I am a novice at SPSS. I have attached pdf images that may help.
