本文讨论了以Cox模型和可加性风险模型为特例的一类一般加性-乘性风险模型下的嵌套病例-控制分析。构造一个伪分数来估计回归参数。所得到的估计量是一致且渐近正态分布的。限定方差-协方差矩阵可以用嵌套的病例对照数据一致地估计。通过仿真研究评估了该估计器的有限样本性能，并给出了一个实例进行说明。
This paper discusses the nested case-control analysis under a class of general additive-multiplicative hazard models which includes the Cox model and the additive hazard model as special cases. A pseudo-score is constructed to estimate the regression parameters. The resulting estimator is shown to be consistent and asymptotically normally distributed. The limiting variance-covariance matrix can be consistently estimated by the nested case-control data. A simulation study is conducted to assess the finite sample performance of the proposed estimator and a real example is provided for illustration.
