MOMENTS OF THE KAPLAN-MEIER ESTIMATOR UNDER NONINFORMATIVE CENSORING
Jiantian Wang (U. S. A.) and Hong-Bin Fang (U. S. A.)
|
Abstract: A
novel noninformative censoring structure is
revealed and the small sample properties of
the Kaplan-Meier estimator and the Nelson
estimator under such noninformative censoring
are studied. The exact bias expressions of
these estimators under proportional hazard
model are derived succinctly without posing
any assumption on the underlying distribution. |
Keywords and phrases: Kaplan-Meier estimator, noninformative censoring, survival analysis. |
