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). This is an internal function. Webtimes `survival_test` lie within the range of survival times `survival_train`. This can be achieved by specifying `times` accordingly, e.g. by setting. `times [-1]` slightly below the maximum expected follow-up time. IPCW … flint street nativity torrent
