WebCalculations for inverse probability of censoring weights (IPCW) Source: R/ipcw.R. The method of Graf et al (1999) is used to compute weights at specific evaluation times that can be used to help measure a model's time-dependent performance (e.g. the time-dependent Brier score or the area under the ROC curve).
