Fitting All the Models and Viewing the Output
E From the menus, choose Analyze > Calculate Estimates to fit all models.
E From the menus, choose View > Text Output.
E In the navigation tree of the output viewer, click the Model Fit node to expand it, and
then click CMIN.
The CMIN table shows the likelihood ratio chi-square statistic for each fitted model.
The data do not depart significantly from any of the models. Furthermore, at each step
up the hierarchy from the Unconstrained model to the Measurement residuals model,
the increase in chi-square is never much larger than the increase in degrees of freedom.
There appears to be no significant evidence that girls’ parameter values differ from
boys’ parameter values.
