WebMar 3, 2024 · I can't think why anyone would care how the test performs at $\alpha \simeq 0.9$, per se.However, the ROC curve is monotonically increasing, so the power at $\alpha\simeq 0.9$ bounds the power elsewhere. In practice the bound is likely to be very weak for $\alpha \lesssim 0.1$ or so of actual interest..

WebAUC (based on ROC) and overall accuracy seems not the same concept. Overall accuracy is based on one specific cutpoint, while ROC tries all of the cutpoint and plots the sensitivity and specificity. So when we compare the overall accuracy, we are comparing the accuracy based on some cutpoint. The overall accuracy varies from different cutpoint. WebThe sensitivity of the COPD-SQ was significantly higher than the COPD-PS (78.3% vs 56.5%, P < 0.001), and the specificity of the COPD-PS was significantly higher than the COPD-SQ (90.2% vs 77.6%, P < 0.001). Similar results were also achieved when using the recommended cut-off scores of COPD-PS ≥ 5 and COPD-SQ ≥ 16 for comparation.
