摘要:
Several situations involving [patient] survival data are examined, in which the nonparametric maximum likelihood estimator is not the Kaplan-Meier estimator. Cases covered are inclusion of initial observations in field studies, estimation of the length distribution from convex window sampling of line segment processes in 2 dimensions and estimation of a survival curve with monotone density. The first 2 case are nonstandard because survival and censoring are not independent and thus form simple tractable variable-sum models.
