## Figure 3.
Relative detection sensitivity of differential gene expression. The number of probe
sets shown to increase from 2 to 5 weeks of murine mammary gland development was tabulated
as a function of the number of probe sets expected to increase by chance. (
a) ChipStat (p_{ps }= 0.05), vs t-test. (b) Optimization of ChipStat sensitivity as a function of p_{ps}. (c) ChipStat vs other techniques: reported P values. For ChipStat, the number of probe sets expected to increase by chance was
empirically estimated from negative control data. For the t-test, SAM, dChip and logit-T, reported P values from the 2-week vs 5-week mammary gland comparison were used. (d) ChipStat vs other techniques: empirical P values. The number of probe sets expected to increase by chance was empirically estimated
for ChipStat, t-test, SAM, dChip and logit-T (representative points).
