Fig. 1.

Standardized loadings and residual correlations resulting from the Confirmatory Factor Analysis (CFA) on the combined tests of the Halstead-Reitan Battery (HRB), Wechsler Adult Intelligence Scales (WAIS/WAIS-R), and expansion of the expanded Halstead-Reitan Battery (eHRB). The CFA model was run by setting one loading in each factor to 1 (indicated by an asterisk), setting the factor means to 0, and letting factor variances vary as parameters. For better interpretability, standardized loadings and residual correlations are presented here instead of unstandardized model parameters. Residual correlations between same-test measures were all significant at p < .001 except when specified.
