Variables used at each time point are latent factors... so the intercepts cannot be estimated. Does this mean there is no way to plot the expected trajectories of each class?

VARIABLE: NAMES ARE A1-A8 C1-C8 D1-D8 SCHOOL;
CLASSES = C(2);
CLUSTER = SCHOOL;
ANALYSIS: TYPE = TWOLEVEL MIXTURE;
MODEL:
%OVERALL%
F1 by A1@1 (L1);
F1 by A2*.1 (L2);
F1 by A3*.1 (L3);
F1 by A4*.1 (L4);

F2 by B1@1 (L1);
F2 by B2*.1 (L2);
F2 by B3*.1 (L3);
F2 by B4*.1 (L4);

F3 by C1@1 (L1);
F3 by C2*.1 (L2);
F3 by C3*.1 (L3);
F3 by C4*.1 (L4);

[A1 B1 C1] (i1);
[A2 B2 C2] (i2);
[A3 B3 C3] (i3);
[A4 B4 C4] (i4);

i s | F1@0 F2@1 F3@2;

Ask for TECH4 in the OUTPUT command. This gives model estimated means of the latent variables in the model.
