Additional file 4 of Picky with peakpicking: assessing chromatographic peak quality with simple metrics in metabolomics

Additional file 4: Figure S3 Robustness of the two most significant metrics across the full (all_params), XCMS-only (xcms_params), and two-parameter (raw_data_params) models. The x-axis corresponds to the fraction of the data used to train the model and the y-coordinate shows the estimated value for the specified term in the subset across tenfold replicated subsampling. The grey bar in the background corresponds to the estimate of the full model ± 1SE (thinner dark grey bar) and 2SE (thicker light grey bar).
