Example 24
cross-group constraints, and the Measurement weights model with factor loadings held
equal across groups, are unidentified.
Viewing the Output
E From the menus, choose View > Text Output.
E In the navigation tree of the output viewer, expand the Model Fit node.
Some fit measures for the four automatically generated and identified models are
shown here, along with fit measures for the saturated and independence models.
E Click CMIN under the Model Fit node.
The CMIN table shows that none of the generated models can be rejected when tested
against the saturated model.
On the other hand, the change in chi-square ( ) when introducing
the equal-factor-means constraint looks large compared to the change in degrees of
freedom ( ).
E In the navigation tree, click the Model Comparison node.
