Statistic Description
Autonomy Proportion of variance that is aligned with a selection gradient and is separate from variation in other directions
Constraints Mean correlation between the response vector to random selection variants and the matrix’s first principal component, which largely constrains the phenotype due to it accounting for much of a species’ phenotypic variation
Flexibility Measure of how close the response of a species aligns with the different random selection gradients
Mean squared correlation Average of the correlation coefficients, corresponding to the overall association between the traits measured
Respondability Pace of the change in population mean when a population is under directional selection
PCA similarity Measure of similarity of the matrices’ variation by incormporating the relative similarity of the matrices’ corresponding principal components
Integration Measure of the strength of morphological integration quantified using the relative eigen index
