双重删失当前状态数据的回归

研究问题
当起始事件与后续事件的时点均不可见,只在随机监测时获知是否已发生时,如何估计两事件间隔的回归关系?
方法与思路
作者采用事件间隔的加速失效时间模型,重点研究起始事件在监测前发生的条件下,其发生时点服从均匀分布的特例。
材料陈述的贡献
摘要称,该特例的似然与起始时点已知时具有相同结构,因此可沿用较简单情形的方法,并报告真实数据应用。
阅读关注点
应核对条件均匀分布假设的含义、监测机制的条件,以及似然结构对应如何支持回归系数的估计。
阅读边界
仅据 Crossref 摘要,无法判断该特例在其他数据中的合理性;摘要未说明完整观测机制、估计性质或应用数值。

原文摘要

SUMMARY Data from settings in which an initiating event and a subsequent event occur in sequence are called doubly censored current status data if the time of neither event is observed directly, but instead it is determined at a random monitoring time whether either the initiating or subsequent event has yet occurred. This paper is concerned with using doubly censored current status data to estimate the regression coefficient in an accelerated failure time model for the length of time between the initiating event and the subsequent event. Motivated by a problem in the epidemiology of acquired immune deficiency syndrome, attention here is focused on a special case, the case in which the initiating event, given that it has occurred before the monitoring time, may be assumed to follow a uniform distribution. The main result is that the likelihood in the special case has the same structure as the likelihood in a simpler setting, the setting in which the time of the initiating event is known. The result allows methods developed for the simpler setting to be applied in the special case. The results of the application of the approach to real data are reported.
