Bootstrapping for Model Comparison
Model 2 is an unrestricted factor analysis with two factors. Note that fixing two of the
regression weights at 0 does not constrain the model but serves only to make the model
identified (Anderson, 1984; Bollen and Jöreskog, 1985; Jöreskog, 1979).
Model 2R is a restricted factor analysis model with two factors, in which the first three
tests depend upon only one of the factors while the remaining three tests depend upon
only the other factor.
