Dear Allstat,
I am carrying out a 3-level repeated measures model in MlWiN and SPSS as follows:
level 1: each BMI reading
level 2: groupd (cases or controls) data come from a cohort based case-control study
level 3: each pair of matched cases and controls (about 1000 pairs)
In MlWiN it is very easy to keep level 2 (group) as a fixed effect. However, I am strugling with SPSS and I could not get exactly the same answer as I got from MlWiN.
Your ideas how to run a 3-level model in SPSS with second level as fixed is very appreciated. Other comments, particulalry on residual covariance type, are most welcome.
All the best
Ghasem
