The patterns were similar to the conditions with two categories. The six polychoric correlation matrices in Study 2 are presented in Tables 3 , 4 , 5 , 6 , 7 and 8.

The analysis model for each matrix is described below. We selected three of the matrices i. The procedure of this simulation is described below:. We first generated continuous data following a standard multivariate normal distribution. The continuous data were analyzed by the normal-theory ML estimator. Therefore, we used the resulting fit indices as the benchmarks for comparison. We categorized the continuous data using threshold values.

For two-category data, we employed [0] or [1] as the threshold value for every item. For four-category data, the thresholds were either [— 1, 0, 1] or [0, 1, 2]. The threshold manipulation was consistent with that at the population level in Study 2.

The unscaled and scaled indices were recorded, and their means are reported in Table 9. The results for the sample-level simulation were consistent with those of Study 2. Reprints and Permissions.

Abstract In structural equation modeling, application of the root mean square error of approximation RMSEA , comparative fit index CFI , and Tucker—Lewis index TLI highly relies on the conventional cutoff values developed under normal-theory maximum likelihood ML with continuous data.

Study 1: Comparing fit indices across estimators using population matrices We employed the simulation technique outlined in Cudeck and Browne to generate polychoric correlation matrices with target degrees of model misspecification as measured by RMSEA U under ML.
