Time-Dependent ROC

When the outcome variable of interest is an event that occurs some time after the test is measured, ROC curves must be time dependent. Two approaches have been proposed by Patrick Heagerty and colleagues. Software and documentation can be obtained here. Alternative approaches have been described in the literature.
