Test whether the following three variance-covariance matrices fit the theoretical confirmatory factor model in Figure 12.3 using LISREL-SIMPLIS. The sample size is 80 for each sample. The variables are entered in order as: SOFED (father's education), SOMED (mothers' education), SOFOC (father's occupation), FAFED (father's education), MOMED (mother's education), and FAFOC (father's occupation).

a. Run individual program for sample 1 to determine CFA model and report CFA parameters.
b. Run individual programs with CFA model on sample 2 and sample 3 and report CFA parameters.
c. Run multiple-sample program to test factor loadings and factor correlations invariant (equal) with unequal error variances and report individual and global chi-square values.
d. Interpret your results.
