The Price of Kaplan–Meier
Kaplan–Meier 估计的代价
Miller has studied the asymptotic efficiency of the nonparametric, Kaplan–Meier survival estimator relative to parametric estimates based on the exponential and Weibull distributions. He concluded that in certain cases, the asymptotic efficiency is low and recommended that analysts give more consideration to parametric estimators, particularly for estimation of small tail probabilities. In this article we revisit this issue and examine the performance of the nonparametric…
