WebIPCW are computed using the Kaplan-Meier estimator, which is restricted to situations where the random censoring assumption holds and censoring is independent of the features. This function can also be used to evaluate models with time-dependent predictions f ^ ( x i, t), such as sksurv.ensemble.RandomSurvivalForest (see User Guide ). 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.
