Canonical correlation analysis (CCA) of the multivariate correlation between three immune traits and multiple dimensions of male color measured via spectrophotometry.

CCA was run first for all four populations combined, after first mean-standardizing each trait within each population, to avoid correlations arising from between-population differences. CCA was then run separately for each lake (except Farewell, due to data corruption). For each CCA, we present the correlation coefficient (r), and an asymptotic approximation to an F statistic and P-value, obtained via the p.asym command in the R package CCP. We also present the loadings of each trait on the canonical x axis (for color) and y axis (for immune traits).Canonical correlation analysis (CCA) of the multivariate correlation between three immune traits and multiple dimensions of male color measured via spectrophotometry.
