Note. Bold indicates preferred solution; AIC=Akaike’s Information Criterion; BIC=Bayesian Information Criterion; SSBIC=sample-size adjusted Bayesian Information Criterion; LMR LRT=Lo-Mendell-Rubin adjusted likelihood ratio test; entropy is reported for descriptive purposes and should not be used for model selection.
