Dear John,
Thanks very much! I don?t know how I didn?t see this before. I checked a
thousand of times....
There is one more thing that I can not understand. What are the possible
reasons for problems on calculation of confidence interval for RMSEA? For the
same model I sent before (after correction of the variable name) the lower CI
output was NA:
Model Chisquare = 10.824 Df = 13 Pr(>Chisq) = 0.62558
Goodness-of-fit index = 0.91656
Adjusted goodness-of-fit index = 0.76895
RMSEA index = 0 90 % CI: (NA, 0.15652)
BIC = -60.425
I have other models with the same behavior, even when the estimative of RMSEA
is different from zero.
Model Chisquare = 15.165 Df = 14 Pr(>Chisq) = 0.367
Goodness-of-fit index = 0.89038
Adjusted goodness-of-fit index = 0.71811
RMSEA index = 0.053558 90 % CI: (NA, 0.19141)
BIC = -61.564
Thanks and all the best.
Andr?
