where n2 = s1+s2-d1. The maximum likelihood estimators are: λ=(s1+s2)/2 (average cohort size), a1=d1/s1, and a2=d2/(s1+s2-d1). Those are the Kaplan-Meier estimators. Notice the formulas depend on cohort sizes s1 and s2? If the ships cohort rates differ, then the maximum l...
Kaplan-Meier estimators of distance distribution for spatial point processes For applications in spatial statistics, an important property of a random set X in Rk is its first contact distribution. This is the distribution of the di... A Baddeley,RD Gill - 《Annals of Statistics》 被引量: 140...
The mid-point imputation is shown to havesmallest mean squared errors at most range of time under moderate to small censoringfor all hazard rates investigated here, although ad hoc estimators of SE underestimatetrue SE. Under heavy censoring, either the right-, mid- or left-point imputations ...
Some computations in the Koziol-Green model give an impression of the magnitude of the bias and variance of the two estimators. Further, we investigate the almost sure convergence of Efron's version of the KM integral in the spirit of {\\\it W. Stute} and {\\\it J.-L. Wang} [Ann...
