- aAbsolute fit: Measures overall goodness-of-fit for the structural and measurement models collectively. This type of measure does not make any comparison to a specified null model (incremental fit measure) or adjust for the number of parameters in the estimated model (parsimonious fit measure)
- bIncremental fit: Measures goodness-of-fit that compares the current model to a specified “null” (independent) model to determine the degree of improvement over the null model
- cParsimonious fit: Measures goodness-of-fit representing the degree of model fit per estimated coefficient. This measure attempts to correct for any “overfitting” of the model and evaluates the parsimony of the model compared to the goodness-of-fit
