The following criteria were used to decide on the number of classes to retain: Akaike information criterion (AIC), Bayesian information criterion (BIC) and sample - size adjusted BIC (adj BIC).54 Also, we used entropy to assess the quality of classification, as well as the Vuong - Lo - Mendell - Rubin (VLMR) adjusted likelihood ratio test for the hypothesis that a model with one less class performs just as well.

To avoid over - or underestimating the importance of each biometric latent factor, we restricted latent genetic (A), shared (C) and nonshared (E) environmental factors to 0 only when their factor loadings were estimated to be close to zero and not based on likelihood ratio tests as is common practice in the behavior genetics literature.

These associations were more pronounced in men than women (likelihood ratio test P for interaction = 0.001; table 2 ⇓ and fig 1 ⇓). (bmj.com)
