What does CFI of 1 mean?
Is this CFA appropriate? In a CFA, we have very good fit indices. For example, the CFI = 1. This, however, is not a just-identified model because degrees of freedom is not 0.
What is a good CFI value?
CFI is a normed fit index in the sense that it ranges between 0 and 1, with higher values indicating a better fit. The most commonly used criterion for a good fit is CFI ≥ . 95 (Hu & Bentler, 1999; West et al., 2012).
What does a TLI over 1 mean?
TLI can be greater than one. It sounds like your model is just-identified with zero degrees of freedom. In this case, model fit cannot be assessed.
What is CFI in factor analysis?
The goodness of fit index (GFI) is a measure of fit between the hypothesized model and the observed covariance matrix. The adjusted goodness of fit index (AGFI) corrects the GFI, which is affected by the number of indicators of each latent variable. The GFI and AGFI range between 0 and 1, with a value of over .
How do you read a CFI?
Comparative Fit Index (CFI) If the index is greater than one, it is set at one and if less than zero, it is set to zero. It is interpreted as the previous incremental indexes. If the CFI is less than one, then the CFI is always greater than the TLI. CFI pays a penalty of one for every parameter estimated.
What is a good CFI SEM?
(b),(c) Value greater than 0.80 suggests a good fit. (d) NFI > 0.9 means satisfactory fit. (b) Value greater than 0.80 suggests a good fit. (a),(d) CFI > 0.9 means satisfactory fit . (b),(d) TLI > 0.9 means satisfactory fit.
What is acceptable RMSEA?
It has been suggested that RMSEA values less than 0.05 are good, values between 0.05 and 0.08 are acceptable, values between 0.08 and 0.1 are marginal, and values greater than 0.1 are poor [8]. Therefore, the RMSEA value of 0.074 in this sample indicates an acceptable fit.
What is a good model fit?
Because the SRMR is an absolute measure of fit, a value of zero indicates perfect fit. The SRMR has no penalty for model complexity. A value less than . 08 is generally considered a good fit (Hu & Bentler, 1999).
How do you read RMSEA?
Model Fit Statistics RMSEA is the root mean square error of approximation (values of 0.01, 0.05 and 0.08 indicate excellent, good and mediocre fit respectively, some go up to 0.10 for mediocre).
How is RMSEA calculated?
RMSEA = SQRT[d/df], with d = chi^2 – df / (N – 1).
What is a good RMSEA value?
between 0.05 and 0.08
It has been suggested that RMSEA values less than 0.05 are good, values between 0.05 and 0.08 are acceptable, values between 0.08 and 0.1 are marginal, and values greater than 0.1 are poor [8]. Therefore, the RMSEA value of 0.074 in this sample indicates an acceptable fit.
