What does RMSEA mean?
root mean square error of approximation
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). In Mplus, you also obtain a p-value of close fit, that the RMSEA < 0.05.
What is CFI and RMSEA?
RMSEA is an absolute fit index, in that it assesses how far a hypothesized model is from a perfect model. On the contrary, CFI and TLI are incremental fit indices that compare the fit of a hypothesized model with that of a baseline model (i.e., a model with the worst fit).
What is SRMR?
Standardized Root Mean Square Residual (SRMR) The SRMR is defined as the difference between the observed correlation and the model implied correlation matrix. Thus, it allows assessing the average magnitude of the discrepancies between observed and expected correlations as an absolute measure of (model) fit criterion.
What is Rmsea in Amos?
RMSEA. Root Mean. Square Error of. Approximation. A parsimony-adjusted index.
What is an acceptable CFI?
CFI values range from 0 to 1, with larger values indicating better fit. Previously, a CFI value of . 90 or larger was considered to indicate acceptable model fit. However, recent studies have indicated that a value greater than . 90 is needed to ensure that misspecified models are not deemed acceptable.
What does CFI measure?
The comparative fit index (CFI) analyzes the model fit by examining the discrepancy between the data and the hypothesized model, while adjusting for the issues of sample size inherent in the chi-squared test of model fit, and the normed fit index. CFI values range from 0 to 1, with larger values indicating better fit.

What is CMIN DF?
CMIN/DF = chi-square fit statistics/degree of freedom; GFI = goodness-of-fit index; AGFI = adjusted goodness of fit index; NFI = normed fix index; RFI = relative fit index; IFI = incremental fix index; TLI = Tucker-Lewis index; CFI = comparative fix index; RMSEA = root mean square error of approximation; RMR = root …
What are modification indices?
The modification index is the χ2 value, with 1 degree of freedom, by which model fit would improve if a particular path was added or constraint freed. Values bigger than 3.84 indicate that the model would be ‘improved’, and the p value for the added parameter would be < .
