Figure 1From: Kernel approaches for differential expression analysis of mass spectrometry-based metabolomics data Histogram of p-values. Histogram of p-values on the simulated data with low group effect, 20% missing data and 50% differentially expressed metabolites. The titles (a), (b), (c), (d), (e), (f) correspond to methods Kernd, Kerns, Qual, Quant, T and Wilcox respectively.Back to article page
