Kaplan-Meier estimator in competing risk contexts

open access: yesHacettepe Journal of Mathematics and Statistics, 2015
Survival analysis has become in a common procedure in biomedical re-searches. Conventionally, the well-known nonparametric Kaplan-Meier(KM) estimator is used in order to approximate the real survivor curve.However, in competing risk contexts where more than one failure causecompete to occur and only one of them is of interest, the direct useof the ...
