Parameter estimates were individually dropped from the full model to test statistical significance. A series of one degree of freedom chi-square difference tests were computed comparing the full model to each model with the dropped parameter. Statistical significance is indicated when dropping the parameter from the model results in a significant decrement in fit. The residual variance parameters could not be dropped from the model; 95% confidence intervals were obtained for the unstandardized estimates to determine statistical significance (not shown; available upon request). Statistical significance of the variance explained by the latent variable was not assessed because the factor loadings were fixed for the first variable in the rater bias model.
