How to do an SEM model with panel data, i dont want to do ordinary regression for each panel/category

When you say panel data, I interpret that as each subject being measured at more than one time point. The analysis depends on whether or not you want to model the development over time, or simply take into account the across-time correlations for each subject. In the former case you do longitudinal modeling such as growth modeling.

Dear Professor,

I have a model of 5 measured variables (x1, x2, x3 , x4 and x5) and 3 latent variables (f1 f2 and f3).

Obaserved variable are being measured at 7 time point for every of the 750 subjects.

x1-x5 and f1 and f2 are time specific (ie indicator of performance for each measuring time)

F3 is a variable that capture the persistence of the agregate performance of each subject.

I am not interested in the effect of time. The purpose is to validate a multidimentional performance construct that evolve over time.

!here i use 3 time points

F11 BY x11@1 x21* x31*
F21 BY F11@1 x11* x21*

F12 BY x12@1 x22* x32*
F22 BY F12@1 x12* x22*
F32 BY F21@1 F22*

F13 BY x13@1 x23* x33*
F23 BY F13@1 x13* x23*
F32 BY F21@1 F22* F23*

The question is:

How should I model this?

Best,
Jean-Samuel

Your approach seems reasonable.
