Figure 4: Trait loadings on the leading vectors of ID (blue points) and IDsex:mass (red points). Error bars denote 95% confidence intervals obtained using a parametric bootstrap (n=5000) and loadings can be considered nominally significant if CI do not cross zero (solid vertical line).
Figure 5: A graphical illustration of the relationship between multivariate personality, mass, and sex. Each point represents an individual’s predicted behavioural score idmaxplotted against mean weight with colours denoting assigned sex (female, male, unknown). Behavioural scores are calculated for each individual asidmax.i T where i is a column vector containing the best linear unbiased predictions (BLUPs) of individual deviations from each trait mean. Also shown for illustrative purpose are overall (grey dashed) and sex-specific regressions of behavioural score on mean weight. Behavioural scores are (uncertain) model predictions and no statistical inference is intended.
