Model Fit statistics for 1- through 4-class solution

Number of classes	Log Likelihood	AIC	BIC	aBIC	VLMR-LRT
1	1912.447	3848.893	3896.791	3858.714	n/a
2	1852.347	3754.695	3854.481	3775.155	p < .0001
3	1834.958	3745.916	3897.592	3777.016	p = .0592
4	1817.798	3737.595	3941.16	3779.334	p = .2218

AIC = Akaike Information Criterion; BIC = Bayesian Information Criterion; aBIC = adjusted Bayesian Information Criterion; VLMR-LRT = Vuong-Lo-Mendell-Rubin Likelihood Ratio test. The two-class solution, shown in bold, was retained for further analysis based on these fit statistics and the substantive interpretation.
