Kaplan–Meier Estimator
The Kaplan–Meier estimator is a nonparametric estimator which may be used to estimate the survival distribution function from censored data. The estimator may be obtained as the limiting case of the classical actuarial (life table) estimator, and it seems to have been first proposed by Böhmer [2]. It was, however, lost sight of by later researchers and not investigated further until the importa...
متن کاملAbout an adaptively weighted Kaplan-Meier estimate.
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. We use the Kaplan-Meier estimate to let the weights accommodate right-censored data and use them to define the weighted Kaplan-Meier esti...
متن کاملSource Code Survival with the Kaplan Meier Estimator
The presence of dead code may affect the comprehensibility, the readability, and the size of source code so increasing the effort and the cost for maintenance. The elimination of dead code needs a huge cost and effort for recognizing and eliminating code that is not effectively used. The goal of this work consists in defining an approach based on the Kaplan Meier estimator to analyze dead code....
متن کاملAsymptotic Properties of Kaplan-meier Estimator for Censored Dependent Data
In some long term studies, a series of dependent and possibly censored failure times may be observed. Suppose that the failure times have a common marginal distribution function, and inferences about it are of our interest. The main result of this paper is that of providing, under certain regularity conditions, the Kaplan-Meier estimator can be expressed as the mean of random variables, with a ...
متن کاملa comparison between kaplan-meier and weighted kaplan-meier methods of five-year survival estimation of patients with gastric cancer.
the 5-year survival rate is a good prognostic indicator for patients with gastric cancer that is usually estimated based on kaplan-meier. in situations where censored observations are too many, this method produces biased estimations. this study aimed to compare estimations of kaplan-meier and weighted kaplan-meier as an alternative method to deal with the problem of heavy-censoring. data from ...
