Table 6:
Estimates for first canonical correlation direction loadings and correlations along with jackknife corrected correlation and bootstrap p-values for canonical correlation analysis between radial diffusivity measures for 20 white matter tracts and five executive function tests in six-year-old children. Estimated for transelliptical canonical correlation analysis using the transformed Kendall’s estimator as well as standard canonical correlation analysis.
