Figure 2From: Identification of expressed genes linked to malignancy of human colorectal carcinoma by parametric clustering of quantitative expression dataDistributions of the first to tenth factor scores obtained by principal component analysis. Vertical axis, number of genes; horizontal axis, factor scores. The interval of each column is 0.3, and the range of the central column is between -0.15 and 0.15. Red curves are normal distributions fitted to the columns. Percent variance explained by each component is as follows, from the first to the tenth: 12.33, 4.96, 4.76, 4.22, 3.28, 3.08, 2.57, 2.51, 2.27, 2.17.Back to article page
