Fig. 3From: Exploring non-linear distance metrics in the structure–activity space: QSAR models for human estrogen receptorPerformance of the GkNN model. Panel a ROC curves for the estimates of agonist activity of the evaluation set chemicals at different confidence values. Panels b, c agonist activities of the evaluation set chemicals estimated using the GkNN model versus those obtained from literature with more than 3 sources and more than 7 sources per chemical, respectively. Color indicates confidence level for each estimateBack to article page
