Definition of abbreviation: BIC = Bayesian information criteria.

Each row represents a single model comprising K classes. N1–N4 are the number of observations in each class and the P value represents the Vuong-Lo-Mendell-Rubin test, which tests whether a model comprising a K class is a better fit than a K-1 class.
