Simultaneous Factor Analysis for Several Groups
Model A is acceptable at any conventional significance level. If Model A had been
rejected, we would have had to make changes in the path diagram for at least one of the
two groups.

Here are the (unstandardized) parameter estimates for the 73 girls. They are the same
estimates that were obtained in Example 8 where the girls alone were studied.
