Model C for the Wheaton Data
Here is the path diagram for Model C from the file Ex06–c.amw:
The label path_p requires the regression weight for predicting powerlessness from
alienation to be the same in 1971 as it is in 1967. The label var_a is used to specify
that eps1 and eps3 have the same variance. The label var_p is used to specify that eps2
and eps4 have the same variance.
