基于R-INLA的竞争风险联合模型

Competing risks joint models using R-INLA

Janet van Niekerk, Haakon Bakka, Haavard Rue

摘要:

在联合模型领域取得的方法进步是多方面的。尽管如此,竞争风险联合模型的情况在很大程度上被忽视了,特别是从从业者的角度来看。在竞争风险联合模型的相关研究中,高斯线性纵向序列和比例原因特定风险函数等假设一直没有受到质疑。在本文中,我们提供了一个框架的基础上R-INLA应用竞争风险联合模型在一个统一的方式,非高斯纵向数据,空间结构,时间依赖样条和各种潜在的关联结构,仅举几例,都包含在我们的方法。我们的动机源于SANAD试验,该试验显示出非线性纵向轨迹和治疗失败的竞争风险。我们还提出了一个离散的纵向计数数据的竞争风险联合模型以及空间竞争风险联合模型,作为具体的例子。

英文摘要:

The methodological advancements made in the field of joint models are numerous. None the less, the case of competing risks joint models have largely been neglected, especially from a practitioner's point of view. In the relevant works on competing risks joint models, the assumptions of Gaussian linear longitudinal series and proportional cause-specific hazard functions, amongst others, have remained unchallenged. In this paper, we provide a framework based on R-INLA to apply competing risks joint models in a unifying way such that non-Gaussian longitudinal data, spatial structures, time dependent splines and various latent association structures, to mention a few, are all embraced in our approach. Our motivation stems from the SANAD trial which exhibits non-linear longitudinal trajectories and competing risks for failure of treatment. We also present a discrete competing risks joint model for longitudinal count data as well as a spatial competing risks joint model, as specific examples.
