本文考虑了失效原因缺失的竞争风险数据分析中原因特异性风险函数的半参数比例风险模型。提出了估计模型中回归参数的逆概率加权方程和增广逆概率加权方程,并建立了它们的理论性质,以便进行推理。仿真研究表明,增广逆概率加权估计具有双重稳健性,该方法适合于实际应用。模拟还比较了所提出的估计与多重插补估计。所提出的方法的应用说明使用骨髓移植研究的数据。
We consider the semiparametric proportional hazards model for the cause-specific hazard function in analysis of competing risks data with missing cause of failure. The inverse probability weighted equation and augmented inverse probability weighted equation are proposed for estimating the regression parameters in the model, and their theoretical properties are established for inference. Simulation studies demonstrate that the augmented inverse probability weighted estimator is doubly robust and the proposed method is appropriate for practical use. The simulations also compare the proposed estimators with the multiple imputation estimator of. The application of the proposed method is illustrated using data from a bone marrow transplant study.
