Figure 5From: Correlation set analysis: detecting active regulators in disease populations using prior causal knowledgeROC curves of ratio score ranking and degree-based ranking. Red and blue ROC curves show ranking by ratio score and by out-degree (e.g. number of coherent expressed targets), respectively. The ROC curves suggest that degree-based ranking is better than random. However, ranking based on ratio score is superior to purely degree-based ranking.Back to article page
