开发了一种方法来获得审查生存数据的树结构相对风险估计。全似然估计过程的第一步用于递归划分算法,该算法采用 Breiman 等人广泛使用的分类和回归树 (CART) 算法的大部分方面。 (1984 年,分类和回归树,贝尔蒙特。加利福尼亚州:Wadsworth)。该技术的性能通过模拟进行了研究,并与 Davis 和 Anderson (1989, Statistics in Medicine 8, 947-961) 以及 Therneau、Grambsch 和 Fleming (1990, Biometrika 77, 147-160) 提出的树结构生存方法进行了比较。
A method is developed for obtaining tree-structured relative risk estimates for censored survival data. The first step of a full likelihood estimation procedure is used in a recursive partitioning algorithm that adopts most aspects of the widely used Classification and Regression Tree (CART) algorithm of Breiman et al. (1984, Classification and Regression Trees, Belmont. California: Wadsworth). The performance of the technique is investigated through simulation and compared to the tree-structured survival methods proposed by Davis and Anderson (1989, Statistics in Medicine 8, 947-961) and Therneau, Grambsch, and Fleming (1990, Biometrika 77, 147-160).
