The same model is estimated for 658 Whites and 171 African-Americans. There appears to be an error in the standard deviation for education of whites. It is changed to .75. The first two variables are indicators of a life change or stress factor. The next three are indicators of a mental health factor.
Stress is assumed to cause mental health.
The model is presented in Figure 1 of the paper. 10.55 The evidence seems to support that the paths and the loadings are invariant, but the variances and covariance are not. They evaluate making that path the only one to be unequal across groups. Testing the for the equality of the covariances makes little sense if the variances are not equal, but it is done so for illustrative purposes only. Go to the SEM page.
