Efficient Estimation of the Cox Model with Auxiliary Subgroup Survival Information
利用辅助亚组生存信息提高 Cox 模型估计效率
With the rapidly increasing availability of data in the public domain, combining information from different sources to infer about associations or differences of interest has become an emerging challenge to researchers. This article presents a novel approach to improve efficiency in estimating the survival time distribution by synthesizing information from the individual-level data with t-year survival probabilities from external sources such as disease registries. While…
