"Factor scores are not the same as the factors in a model. How close they are to each other can be seen in the factor determinacy score. See the FSDETERMINACY option of the OUTPUT command."
1) I wonder why they are not the same? Why aren't the same scores saved so they can be used as dependent variables for regression? 2) In another thread Linda said that these fscores can't be used as dependent variables in regression. Why is this? 3) Is there any way I can save the factors from CFA (for example the STDYX outcomes) as they are in the model and use these for regression as dependent variables?
In this case, look at the information function plots which tell you the precision with which the factor scores are estimated for different values of the factor. The information function value is 1/SE**2. The higher the value, the more precise the factor scores.
