Example 12
Model A for the Holzinger and Swineford Boys and Girls
Consider the hypothesis that the common factor analysis model of Example 8 holds for
boys as well as for girls. The path diagram from Example 8 can be used as a starting
point for this two-group model. By default, Amos Graphics assumes that both groups
have the same path diagram, so the path diagram does not have to be drawn a second
time for the second group.
In Example 8, where there was only one group, the name of the group didn’t matter.
Accepting the default name Group number 1 was good enough. Now that there are two
groups to keep track of, the groups should be given meaningful names.
Naming the Groups
E From the menus, choose Analyze > Manage Groups.
E In the Manage Groups dialog box, type Girls for Group Name.
