Figure 3.

The relationship between log(index) and log(RNA) for each model using the Affymetrix dataset. Plots of log RNA concentration versus (a,d) log(MAS5); (b,e) log(dChip PM-only), and (c,f) RMA. (a-c) show results for all 14 spiked genes and least-squares regression line through aggregate data. (d-f) show data for one probe set, 37777_at, with least squares regression line.
