optAUC: Optimal Combinations of Diagnostic Tests Based on AUC

Share:

Searches for optimal linear combination of multiple diagnostic tests (markers) that maximizes the area under the receiver operating characteristic curve (AUC); performs an approximated cross-validation for estimating the AUC associated with the estimated coefficients.
