Table 2. Model rank, model name, model parameter estimates, log-likelihood, log(L), AIC, and Akaike weights for all eight heterogeneous rate or correlation multivariate Brownian evolution models of Table 1, fit to overall size and relative body depth in South American iguanian lizards (Fig. 2).

Column headers are as in Table 1, except for w, which indicates Akaike weight as calculated using Eq. (4).
