Table 3.
The experiment results for the myocardial infarction (Edin), the cancer biomarker (CA), and the length of hospitalization (THA) datasets. The evaluation metric is the averaged full area under the receiver operating characteristic curve (AUC) among N sites, for 30 trials. The Pearson Correlation Coefficient (PCC) was computed to evaluate the linear correlation between 2 methods. Finally, the alpha in the 2-sample t-test was 0.05, and the p-values larger than 0.05 (shown in bold italic) indicate no statistically significant difference between the AUC results of EXPLORER and ExplorerChain
