基于标记过程的一致预测规则框架

研究问题
在生存分析中,如何利用个体内部标记过程的历史预测未来失效时间,并使不同时间的信息与预测规则保持一致?
方法与思路
作者建立预测函数的随机框架,提出其应满足的一致性条件,讨论一般构造方式,并以多个例子分析插补方案。
材料陈述的贡献
摘要称,部分已有插补方案不满足该一致性条件;该条件也帮助解释替代响应模型,并延伸至相关的反向预测问题。
阅读关注点
应核对一致性条件的准确含义、预测所条件化的历史信息,以及插补反例和反向预测问题的具体设定。
阅读边界
OpenAlex 索引摘要未注明稿件版本;这里的一致性条件不能自动等同于估计量渐近一致性,摘要未说明预测准确率。

原文摘要

Recently interest has developed regarding the statistical properties and uses of marker processes in the context of the analysis of failure time data or survival analysis. A marker process is a stochastic process that acts as a time dependent covariate that is internal to the unit under study in the language of Kalbfleisch & Prentice (1980). As such the sample path of the process up to a certain point in time may carry information about the subsequent hazard for failure. Uses of marker processes in the analysis of survival data are manifold. Here we consider the specific area of prediction of future failure times at a point in time based on various forms of information about the history of the marker process. We provide a stochastic framework for the consideration of prediction functions, demonstrate a simple consistency condition that such functions should satisfy, and discuss construction of prediction functions in a general sense. Several examples are used to illustrate the ideas and we show that certain recently suggested imputation schemes fail to meet the consistency condition. The consistency condition also elucidates the model assumed by Cox (1983) in his work on surrogate responses. We also briefly consider a closely related backward prediction problem.
