The Nelson–Aalen and Kaplan–Meier Estimators Under a Sequential Sampling Scheme
This article deals with some statistical properties of the modified Kaplan–Meier and Nelson–Aalen estimators defined for a right-censored sample under a certain sequential sampling scheme. Both types of estimators were proposed by Rossa in the article “Estimation of Survival Distributions Under Right-Censoring When Sample Size Is Random” (Sequent. Anal. 2008, 27(2), 174–184).
