Hi -
The MIXED procedure in SPSS can not handle binary outcomes. You would need
to use different software such as HLM or MLwiN. SAS or R may be able to
handle binary outcomes, as well, although I am not 100% sure they can.

Subject: longitudinal binary data question
Hi everyone,
I am trying to find out if SPSS can analyze longitudinal binary data. We
have two patient groups, and we are following them over 4 time points - and
the physician seeing each subject codes whether or not they are symptomatic
(yes or no) at each time point. I know I can't do repeated measures ANOVA
on this because the data are binary. Would this work in mixed models in
SPSS? I've tried clicking on mixed models, but I'm getting lost.
Any helpful hints greatly appreciated.
Thanks!
