3.3 Y-randomized analysis
We repeated 1000 Y-randomized validation trials to ensure the reliability of the results. As was shown in Figure 6, The meanR 2Y andQ 2Y of 1000 Y-random tests of critical properties model were far lower thanR 2 and Q 2 of the original model. The comparison of the meanR 2Y andQ 2Y of Y-random test is shown in Figure 6. This indicates that our model has no chance correlation in the modeling process.
