The gene expression parameters. These parameters (Table 2) were estimated by using the EM-algorithm (see "gene expressions" in the implementation section). The vertical lines constitute a stem-plot of the data. The red, green and blue curves indicate down-, not-, and up-regulated genes, respectively. The black curve is a combination of the three curves and, hence, the distribution of the logratios.
