Table 2: Descriptions of the different statistics used to compare the P matrices of focal groups. These statistics come from the EvolQG package (Melo et al. 2015) and the geomorph package (Baken et al. 2021; Adams D, Collyer M, Kaliontzopoulou A 2023), and complete details can be found there. Briefly, the autonomy, constraint, flexibility, mean squared correlation, respondability, and integration statistics provide point estimates that serve as descriptions of a single group’s P matrix. On the other hand, PCA similarity statistics provide estimates of similarity between two P matrices.
