基于最大化二叉树中的节点所代表的患者组之间的生存差异，开发了一种用于审查生存数据的基于树的方法。该方法包括具有类似于分类和回归树（CART）修剪算法的最佳属性的修剪算法。讨论了条件累积风险和生存函数估计的均匀收敛，并给出了一个例子来说明该算法在为患者制定预后分类时的实用性。
A tree-based method for censored survival data is developed, based on maximizing the difference in survival between groups of patients represented by nodes in a binary tree. The method includes a pruning algorithm with optimal properties analogous to the classification and regression tree (CART) pruning algorithm. Uniform convergence of the estimates of the conditional cumulative hazard and survival functions is discussed, and an example is given to show the utility of the algorithm for developing prognostic classifications for patients.
