The circle shows the correlation between the original variables and the two new components. a = female standardized dominance rank, b = female leadership score, c = female age. Pearson correlations between factor 1 of the PCA and the original variables were: −0.95 (a), −0.99 (b), −0.97 (c); Pearson correlations between factor 2 and the original variables were: −0.31 (a), 0.09 (b), 0.21 (c).
