“…The reliability of the predictions was confirmed by the determination of the error bias of the model . This verifies the absence of systematic error, assuring that error values lie both above and below the null residual.…”

“…According to the results of the prediction evaluations, our models performed well and can markedly decrease the false‐positive rate in prediction compared with other previous models. Afterward, we chose three simple but important descriptors—molecular weight (MW), lipo‐hydro partition coefficient (LogP), topological polar surface area (TPSA)—to define the applicability domain (AD) of our model and analyzed the significance of these descriptors in the mechanism of BBB penetration . Also, substructure frequency analysis and information gain (IG) method were used to identify several representative substructures of BBB+ and BBB− by using SARpy tools.…”

“…The estimated predictive power of the models is evaluated on the test set by calculating the root-mean-squared error in prediction (RMSE; error-based metric) and correlation metrics (e.g., R 2 ; correlation-based metric) for the predicted against the observed values (Kuhn & Johnson, 2013;Roy, Ambure, & Aher, 2017). The values for these metrics can be calculated using the camb functions Rsquared_CV and RMSE_CV (see section 4 of Supplementary File 3).…”
