Canonical variable distribution of principal components for (a) stage 1, (c) stage 2, and (e) stage 3 measurements and the score plots of the first principal component (PC 1) against the intermediate- and high-order PCs for (b) stage 1, (d) stage 2, and (f) stage 3 measurements. The clustered principal components (centered on origin) had poor discrimination of scores and were therefore discarded from the analysis.
