Figure 2From: Kernel approaches for differential expression analysis of mass spectrometry-based metabolomics data ROC curve. ROC curves of different methods on the simulated data with low group effect, 20% missing data and 50% differentially expressed metabolites. The range of y-axis on the left panel a) is [0,1], and the range of y-axis on the right panel b) is [0.9,1].Back to article page
