Identification of chemical composition alterations of developing chick corneas using PCA-LDA computation of XRF spectra. (A) Two-D PCA-LDA scores plot of chick corneas at different developmental days: day 12 (red squares) vs. day 14 (blue circles) vs. day 16 (green triangles). (B) PCA-LDA loadings plot of developmental chick corneas at day 12, day 14, and day 16 with linear discriminant components (LDs) as follows: LD1 (red) and LD2 (blue). (C) Corresponding PCA-LDA cluster vectors plot of developmental chick corneas at day 12 vs. day 14 vs. day 16.
