- Each nested model contains its constraints, plus the constraints of all previous, tenable models. Invariance was evaluated with RMSEA Model Test and examination of the Comparative Fit Index (CFI) and the Tucker-Lewis Index (TLI) For example, if the RMSEA from the weak factorial model was within the 90% RMSEA confidence interval (RMSEA 90% CI) for the configural invariant model, and the change in CFI was less than .01 (see Cheung & Rensvold, 2002), and the change in TLI was less than .01, then the constraint was deemed tenable invariance was established
