An extended Kaplan-Meier estimator and its applications

Statistics in Medicine, 1998
We develop an extension of the Kaplan-Meier estimator for the case of multiple live states. The method can be used to construct prognostic charts for tracking individuals initially in a given condition. It is also the key component in constructing a longitudinal version of the multistate life table.

About an adaptively weighted Kaplan-Meier estimate

Lifetime Data Analysis, 2009
The minimum averaged mean squared error nonparametric adaptive weights use data from m possibly different populations to infer about one population of interest. The definition of these weights is based on the properties of the empirical distribution function.

A Note on Pooling Kaplan-Meier Estimators

Biometrics, 1993
SUMMARY Suppose we have several independent samples of censored data, with possibly different censoring patterns for each sample but a common lifetime distribution. Here we examine the problem of how to efficiently combine the information from all the samples to form an estimator of the common survival function.

Discrepancy with respect to kaplan-meier estimator

Communications in Statistics - Simulation and Computation, 1998
As first step of applying the Number-theoretic method to Survival Analysis, we suggest the discrepancy associated with Kaplan-Meier estimator. The convergence rate is still O(n-1:) in some sense. Further studies are given and the simulation results are reported.

Presmoothed Kaplan–Meier and Nelson–Aalen estimators

Journal of Nonparametric Statistics, 2005
In this paper a modiÞcation of the Kaplan-Meier and Nelson-Aalen estimators in the right random censorship model is studied. The new estimators are obtained by replacing the censoring indicator variables in the classical deÞnitions by values of a nonparametric regression estimator. Asymptotic normality is obtained and it is shown that this presmoothing

On an exponential bound for the Kaplan–Meier estimator

Lifetime Data Analysis, 2007
We review limit theory and inequalities for the Kaplan-Meier Kaplan and Meier (J Am Stat Assoc 53:457-481, 1958) product limit estimator of a survival function on the whole line [Formula: see text] . Along the way we provide bounds for the constant in an interesting inequality due to Biotouzé et al.

Efficiency Loss with the Kaplan-Meier Estimator.

1985
Abstract : We consider the proportional hazards model where the distribution G of the censoring random variable is related to the distribution F of the lifetime random variable via (1 - G)=(1 - F) to the beta power. Nonparametric estimators of F are developed for the case where beta is unknown and the case where beta is known.
