2. There are similarities and differences between all fit statistics. Table 2 NFI CFI RMSEA NFI Compares Χ² TESTED MODEL to Χ² BASELINE MODEL Assumes measured variables are uncorrelated. CFI Assumes noncentral Χ² distribution RMSEA Compares sample COV matrix and population COV matrix
1. Researchers should consult several fit statistics when evaluating model fit.
Fit indices were developed with different rationales.
No single index will meet all our expectations for an ideal index
