Fig 2
Results of white oak tree data.
A: Two-dimensional representations of samples colored by continental origins after conducting AC-PCoA, PCoA, and aPCoA using six distance measures. B: MANOVA F-statistic, NMI of k-means clustering, and classification accuracy. Continental origins are set to be the true labels. MANOVA test, k-means clustering, and classification were conducted on two and three principal coordinates from PCoA, AC-PCoA, and aPCoA.
