q-RASAR
The novel quantitative read-across structure-activity relationship (q-RASAR) approach clubs the advantages of both QSAR and read-across, thus resulting in enhanced productivity for the same level of chemical information used. This approach utilizes the similarity- based considerations yet can generate simple, interpretable and transferable models. This approach may be used for any type of structural and physicochemical descriptors and with any modeling algorithms.
