Histograms of the 20 genes selected most frequently in 1000 randomly selected training samples when forming classification rules involving 1, 5, 20, and 50 genes. The horizontal axis is the percent of all classification rules (with the indicated number of genes) for which the gene appears. Each horizontal bar represents a different gene.
