Methods for the Analysis of Sampled Cohort Data in the Cox Proportional Hazards Model
Cox比例风险模型中抽样队列数据的分析方法
Methods are provided for regression parameter and cumulative baseline hazard estimation in the Cox proportional hazards model when the cohort is sampled according to a predictable sampling probability law. The key to the methodology is to define counting processes which count joint failure and sampled risk sets occurrences and to derive the appropriate intensities for these counting processes, leading to estimation methods parallel to those for full cohort data. These…
