Expert Kaplan--Meier estimation [PDF]

open access: yes, 2022
The setting of a right-censored random sample subject to contamination is considered. In various fields, expert information is often available and used to overcome the contamination. This paper integrates expert knowledge into the product-limit estimator in two different ways with distinct interpretations.

Sample size calculations for single‐arm survival studies using transformations of the Kaplan–Meier estimator [PDF]

open access: yesPharmaceutical statistics, 2020
In single‐arm clinical trials with survival outcomes, the Kaplan–Meier estimator and its confidence interval are widely used to assess survival probability and median survival time. Since the asymptotic normality of the Kaplan–Meier estimator is a common

Doubly robust estimator of risk in the presence of censoring dependent on time-varying covariates: application to a primary prevention trial for coronary events with pravastatin

open access: yesBMC Medical Research Methodology, 2020
Background In the presence of dependent censoring even after stratification of baseline covariates, the Kaplan–Meier estimator provides an inconsistent estimate of risk.

A Generalized Kaplan-Meier Estimator

open access: yesThe Annals of Statistics, 1984
A class of nonparametric maximum likelihood estimators of the survival function based on incomplete or right-censored data is derived in the general situation that the time to death and the time to loss (censoring) are not necessarily independent. This is the competing risks problem with two causes of failure.
