Figure 7.

Power analysis for detecting joint differential expression. Receiver operating characteristic (ROC) curves that display the fraction of false positives, or discriminatory ability, in our simulation study to detect joint differential expression. The left panel summarizes information about the gap/substitution scenario; the right panel is about the on/off scenario. The solid lines correspond to CorScor, and the dashed ones, to logistic regression. Finally, the strength of joint differential expression was set at five different levels in our simulation experiment. The yellow lines are for the weakest amount of joint differential expression and the black lines, for the strongest amount.
