Note: The full model refers to the full bivariate model seen in Figure 1. −2LL = −2 log-likelihood; df = degrees of freedom; AIC = Akaike Information Criterion, BIC = Bayesian Information Criterion; ΔLL = difference in log-likelihood; Δdf = difference in degrees of freedom.

Note: The full model refers to the full extended univariate model seen in Figure 2. −2LL = −2 log-likelihood; df = degrees of freedom; AIC = Akaike Information Criterion, BIC = Bayesian Information Criterion; ΔLL = difference in log-likelihood; Δdf = difference in degrees of freedom.
