研究了递归划分过程的稳定性方面。使用重采样技术，引入了评估单分裂稳定性和整体树稳定性的诊断工具。为了纠正程序对具有许多独特实现的协变量的偏好，在算法的因子选择组件中使用了校正后的 p 值。最后，讨论了稳定基于树的预测器的方法。版权所有 (C) 2000 John Wiley & Sons, Ltd.
Stability aspects of recursive partitioning procedures are investigated. Using resampling techniques, diagnostic tools to assess single split stability and overall tree stability are introduced. To correct for the procedure's preference for covariates with many unique realizations, corrected p-values are used in the factor selection component of the algorithm. Finally, methods to stabilize tree-based predictors are discussed. Copyright (C) 2000 John Wiley & Sons, Ltd.
