AIC=Akaike information criterion; BIC=Bayesian information criterion; ABIC=Sample-size adjusted Bayesian information criterion; LMR LR= Vuong-Lo-Mendell-Rubin likelihood ratio test; AMR LR= Adjusted Vuong-Lo-Mendell-Rubin likelihood ratio test; BLRT=Parametric bootstrapped likelihood ratio test. Better model fit is indicated by lower akaike, Bayesian, and adjusted Bayesian information criteria, higher entropy values, and significant p-values for the Vuong-Lo-Mendell-Rubin, adjusted Vuong-Lo-Mendell-Rubin, and parametric bootstrapped likelihood ratio tests; bolding indicates better values for each of these characteristics
