Plots of means and 95% confidence intervals for the unrestricted means (left) and fixed parameter (right) 5-class models. The fixed parameter model specifies a class with means of −0.5 (Low Average) and +0.5 (High Average). Numbers in parentheses are estimated proportions for each class (unrestricted/restricted). Note these values generally do not shift much, implying stability of the models. Profile means (y-axis) are standardized within the sample. SSRT stop-signal reaction time, VRT go-reaction time variability, FSIQ full-scale IQ, Digit Span Fwd digit span forward, Digit Span Bkwd digit span backward. Class proportions are depicted in parentheses (unrestricted model/restricted model)
