Figure 11.

Probability of observing at least k genes in three trials. Figure shows the number of probe sets observed in all three trials, assuming that only random differences exist among the gene expressions. Each trial selects randomly 63 probe sets out of 632, corresponding to the number of the probe sets above (below) the 0.8 probability interval. The circles and solid line correspond to the calculations based on binomial probability and triangles represent the results of Monte Carlo simulations (400 runs).
