Fig. 4From: 6D-QSAR for predicting biological activity of human aldose reductase inhibitors using quasar receptor surface modelingApplicability domain using Williams plot for (a) 3D-QSAR model, (b) 6D-QSAR model (GOLD), and (c) 6D-QSAR model (AutoDock). Standardized residuals are plotted vs. the leverage values for each compound. Circle and triangle shapes are used to demonstrate training and test datasetBack to article page
