Model fit for the optimal number of classes characterized by outpatient satisfaction.

Model	Log-Likelihood	Resid. df	BIC	ABIC	AIC	CAIC	Entropy
Class 1	−6125.09	640	12,393.08	12,323.23	12,294.18	12,415.08	-
Class 2	−4638.71	617	9569.71	9426.83	9367.42	9614.71	0.96
Class 3	−4486.68	594	9415.04	9199.14	9109.365	9483.04	0.88
Class 4	−4416.67	571	9424.41	9135.48	9015.34	9515.41	0.83
Class 5	−4338.59	548	9417.64	9055.69	8905.18	9531.64	0.85

Note: Resid. df = degrees of freedom of residuals; BIC = Bayesian Information Criterion; AIC = Akaike information criterion; ABIC = adjusted BIC, CAIC = consistent AIC. The 3-class model in bold had the smallest BIC value.
