Ok, sorry I forgot about the Thurstone example as I was focusing on Path
Analysis example when reading the sem doc.
I understand this is a model taken from another source.
In the model specification I notice a F4->F1, F4->F2, F4->F3.
This is something I do not understand.
In a "normal" case where one is iterested in the factorial validity of the
indicator variables, would it be appropiate to use the same specification
just omitting the above links?
