From: Metabolomic biomarkers correlating with hepatic lipidosis in dairy cows

Figure 3

Combined principal component and linear discriminant analysis. This model reveals that 29 endogenous metabolites, in conjunction, distinguish dairy cows with different stages of hepatic lipidosis (groups 2–4) from reference animals (group 1) lacking the characteristic lipid deposition in their liver. The centroid, or center of mass, were computed from the coordinates of all points in each group. The linear functions for the two main discriminant factors [F (x1) and F (x2)] are laid down in the “Methods” section.
