Figure 2.

The dot-plot of F-values versus $\overline{f}$-values. F-values and $\overline{f}$-values obtained from the simulated microarray data of 3770 genes were ranked where $\overline{f}$-values were yielded by the random splitting approach. All ranked F - $\overline{f}$ dots roughly fall on a diagonal line as expected by two sets of the same ranked distributions.
