Nonparametric analysis of changes in hazard rates for censored survival data: An alternative to change-point models
删失生存数据中风险率变化的非参数分析：变点模型的替代方案
As a nonparametric estimator for the point of the most rapid change of a hazard rate we propose the location of an extremum of a nonparametric estimate of the derivative, or equivalently, of a zero of a nonparametric estimate of the second derivative. Using the kernel method for the nonparametric estimation of derivatives of the hazard rate, the asymptotic local limiting distribution and uniform consistency are applied to prove consistency and to find the limiting…
