SPSS simultaneous equation models analysis with panel data



Hi to everybody,

I've just created four cross sectional models based on panel data with MIXED MODEL procedure.
Now I'd like to made a simultaneous equation models analysis.
Do you know how I can do it?
Do I need AMOS?
And if yes, does anyone know whether there is a specific tutorial available on web which I can use to solve my problem?
Thank you in advance!
