跨人群的半参数单指数风险评分

研究问题
如何综合不同疾病与人群的信息估计共同饮食评分,同时允许各组具有不同的线性部分,并限制非参数响应函数仅有尺度差异?
方法与思路
作者采用部分线性单指数模型,令饮食指数跨疾病与人群共享,以节点数递增的 B 样条估计相关函数并研究渐近理论。
材料陈述的贡献
摘要称,方法实现跨疾病和人群的联合建模,并在 NIH-AARP 饮食与健康研究中展示联合分析牛奶摄入信息的优势。
阅读关注点
核对共同指数的识别与归一化、函数仅相差尺度的限制、样条节点增长条件,以及组间异质性对联合估计的影响。
阅读边界
仅据版本未注明的 OpenAlex 索引摘要,不能推断刊本变化。摘要未说明渐近条件、模型限制的检验或应用数值,风险关联不能直接解释为因果效应。

原文摘要

We consider a problem motivated by issues in nutritional epidemiology, across diseases and populations. In this area, it is becoming increasingly common for diseases to be modeled by a single diet score, such as the Healthy Eating Index, the Mediterranean Diet Score, etc. For each disease and for each population, a partially linear single-index model is fit. The partially linear aspect of the problem is allowed to differ in each population and disease. However, and crucially, the single-index itself, having to do with the diet score, is common to all diseases and populations, and the nonparametrically estimated functions of the single-index are the same up to a scale parameter. Using B-splines with an increasing number of knots, we develop a method to solve the problem, and display its asymptotic theory. An application to the NIH-AARP Study of Diet and Health is described, where we show the advantages of using multiple diseases and populations simultaneously rather than one at a time in understanding the effect of increased Milk consumption. Simulations illustrate the properties of the methods.
