Figure 3.

Data preprocessing - with normalisation. The plot of ranked mean of probe intensities versus their standard deviation for the g-log transformed and quantile normalised data. The standard deviation shows relatively constant variation when compared to the mean intensities. The solid red line is a lowess smooth line of the probe intensities.
