Supplementary Information 2 from On the lack of a universal pattern associated with mammalian domestication: differences in skull growth trajectories across phylogeny

Results of multivariate analyses of cranial allometry for the domesticated and wild forms investigated. The first three data columns show results using all specimens. The remaining columns show jackknife results calculated with untrimmed and trimmed (m = 1) sets of pseudovalues (see Giannini et al., 2004 for details). The allometric coefficient of a variable is the corresponding element of the first (unit) eigenvector per variable. The expected coefficient is the value under the assumption of isometry (0.267 for all variables). The observed coefficient is the value obtained with all specimens included. The resampled coefficient is the value generated by first-order jackknife resampling. Bias is the difference between the resampled and observed coefficients. The jackknifed 95% confidence interval (CI) is provided; allometric variables are those whose CIs exclude the expected value under the assumption of isometry (0.267). Abbreviations as in Fig. 2. ISO, isometry; POS, positive allometry, NEG, negative allometry
