Figure 2.

Fisher discriminant analysis plot of mouse liver samples. Samples were scored according to the canonical variables determined by Fisher Discriminant Analysis (FD Analysis). Each canonical variable is defined as a weighted sum of 100 specific genes. To score a sample, the gene expression value is multiplied by an FD Analysis coefficient, called a loading, and the products from the 100 genes used in the analysis are summed to give the canonical variable score for the sample.
