Abbreviations: K = degrees of freedom; AIC = Akaike information criterion; BIC = Bayesian information criterion; aBIC = adjusted Bayesian information criterion, the smaller the statistical value, the better the model fit. BLRT = likelihood ratio test (Bootstrap-based BLRT); LMR = Vuong-Lo-Mendell-Rubin test.
