The KaplanMeier (product-limit) estimator of the survival function of randomly censored time-to-event data is a central quantity in survival analysis. It is usually introduced as a non-parametric maximum likelihood estimator, or else as the output of an imputation scheme for censored observations ...
The KaplanMeier estimator as an inverse-probability-of-censoring weighted average. Amer. Statist. Ass. 55:207210) showed that the KaplanMeier estimator (product-limit estimator (PLE)) can be expressed as an inverse-probability-weighted average. In this article, we consider the other two PLEs: ...
proposed for comparing group differences of survival functions. Simulation studies are used to illustrate the performance of AKME and the weighted log-rank test. The method proposed here outperforms the Kaplan-Meier estimate, and it does better than or as well as other estimators based on ...
We note that, for IPCW, Kaplan–Meier is applied to estimate the distribution of censoring times, whereas it is much more commonly used to estimate the distribution of event times. 2. For each patient i in the training set, define an inverse probability of censoring weight,(1)ωi=1Ĝ{...

Estimates survival using inverse probability of treatment weighted (IPTW) Kaplan-Meier estimationLayla Parast
Specifically, a Kaplan–Meier approach based on a modified risk set and the proposed inverse censoring approach lead to different estimators. Furthermore, when both censoring variables are always observed, as in the case of an AIDS clinical trial data set analyzed in this paper, an alternative ...
Kaplan-Meier estimatorright-censoringIn this paper, we study a class of empirical processes associated with U-statistics in the context of right-censored data when the censoring is independent, and the censored data is reweighted using the inverse of survival function of the censoring random ...
