plot_roc.RdPlot IPCW ROC curve for a prediction
plot_roc(time, delta, marker, wts = NULL, tao, method)
| time | vector of (censored) event-times |
|---|---|
| delta | vector of event indicators at the corresponding value of the vector time. Censored observations must be denoted by the value 0. |
| marker | vector of the marker values for which we want to compute the time-dependent ROC curve. the function assumes that larger values of the marker are associated with higher risks of events |
| wts | IPC weights |
| tao | evaluation time point of interest |
| method | IPCW or discard |
