Fit statistics for one to three class models of cognition

Fit index	One class	Two classes	Three classes
AIC	11639.86	11322.12	11246.24
BIC	11746.10	11484.27	11464.31
ssBIC	11625.95	11300.90	11217.70
Entropy		0.89	0.91
LMR		353.01^**	114.68
BLRT		356.68^***	115.87^***

Note: AIC = Akaike information criterion, BIC = Bayesian information criterion, ssBIC = sample-size-adjusted Bayesian information criterion, LMR = Lo-Mendell-Rubin test, BLRT = bootstrap likelihood-ratio test. Italics indicate the best-fitting number of classes. Best fitting values of Entropy are those closer to 1.0.
