Dear Pref. Fox
Sorry, I didn't receive your reply. I try the new sem package. It's
great. The following is the results that I got. The fit indices are
Model Chisquare = 208 Df = 98 Pr(>Chisq) = 6.6e-10
Chisquare (null model) = 1741 Df = 120
Goodness-of-fit index = 0.9
Adjusted goodness-of-fit index = 0.87
RMSEA index = 0.066 90 % CI: (0.054, 0.079)
Bentler-Bonnett NFI = 0.88
Tucker-Lewis NNFI = 0.92
Bentler CFI = 0.93
BIC = -336
Thank you very much. You help me out so many problems.
