Figure 2.

Comparison of Average Difference values with Δ_h and randomly selected Δs. For each of the datasets shown, the proportion of genes whose Δ_h value is within twofold of the Average Difference is shown by the black bars. The same comparison is shown for random s (gray bars). Error bars indicate standard deviation. Standard deviation shown reflects variations in the percentage of genes within twofold of the Average Difference between the 176 chips of the training set. Note that the Δ_hs better approximate the Average Difference compared to randomly selected Δ s.
