Fig. 2

ROC curves of texture analysis parameters in distinguishing between luminal A and luminal B types. Sum entropy (dotline), Sum variance (dash line), and predictive model combining sum entropy and sum variance (solid line) are shown. Diagonal line represents AUC of 0.50. The ROC curves represent the complete data set, please refer to text for LOOCV results. AUC values are given in Table 3.
