On the Use of Min-Max Combination of Biomarkers to Maximize the Partial Area under the ROC Curve

Table 1

Means (standard deviations) of the partial area under the ROC curve for different combination methods based on the dataset consisted of ratings from multivariate normal distributions with equal variance-covariance matrices (scenario#1) with 1000 simulated datasets.
