摘要

在生存分析中，许多队列研究都包含了由事故病例和流行病例组成的子队列。与单独分析事件队列和流行队列的数据相比，将这两个子队列的数据结合起来肯定有其优势。在本文中，我们讨论了使用长度偏右删失流行队列数据和右删失事件队列数据的生存函数非参数极大似然估计法（NPMLE）。我们建立了生存函数 NPMLE 的渐近特性，并利用 NPMLE 估算了在蒙特利尔地区医院花费时间的分布。

The survival function NPMLE for combined right-censored and length-biased right-censored failure time data: properties and applications

Many cohort studies in survival analysis have imbedded in them subcohorts consisting of incident cases and prevalent cases. Instead of analysing the data from the incident and prevalent cohorts alone, there are surely advantages to combining the data from these two subcohorts. In this paper, we discuss a survival function nonparametric maximum likelihood estimator (NPMLE) using both length-biased right-censored prevalent cohort data and right-censored incident cohort data. We establish the asymptotic properties of the survival function NPMLE and utilize the NPMLE to estimate the distribution for time spent in a Montreal area hospital.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
