Fig. 4From: Putative biomarkers for predicting tumor sample purity based on gene expression dataBox plots of cross-validation performance using the ten marker genes for each of the 33 tumor types: a, RMSE; and b, Pearson correlation. The white box extends from the 25th to the 75th percentiles with the median at the horizontal line. Based on median RMSE, the three tumor types (LAML, PAAD, and THYM) performed relatively poorly compared to others (red arrows)Back to article page
