Figure 1From: Reliable estimation of prediction errors for QSAR models under model uncertainty using double cross-validationBias terms (TS-MLR, TS-PCR, simulation model 2). Average bias terms of the model errors (ave.bias (ME )) for simulation model 2. The bias varies depending on the regression technique (TS-MLR, TS-PCR), different cross-validation designs in the inner loop, and test set size in the outer loop.Back to article page
