I have longitudinal data collected on about 200 students from 30 school programs. Each school program is randomized to administer manipulation A or manipulation B to students that belong to that school program.
I would like to build a GMM to characterized the students response over time. How do I take into account that the students are nested within school programs?
Below are my code without taking into account the nesting within school programs.

Title: GMM
Data: file is 'file.dat';
Variable: names are Treatment T1 T2 T3 T4;
Analysis: type=MIXTURE;
STARTS=200 10;

Model: %OVERALL%
i s|T1@0 T2@2 T3@3 T4@4;
c#1 ON Treatment;
c#2 ON Treatment;

Output: sampstat standardized tech1 tech8 tech11;
PLOT: SERIES=T1 T2 T3 T4 (s);
Thanks in advance for your help!
