Figure 2.

Histogram of average probe intensities ${\overline{\mathit{y}}}_p=1/R{\displaystyle \sum {}_{r=1}^R}{y}_{pr}$ from Rap1 yeast experiment. The density estimates from the proposed model fit are overlayed, and the two component mixture of both Enriched and not Enriched probes is evident. This figure appears in color in the electronic version of the article.
