We propose a method to screen group variables under the high dimensional group variable setting for the proportional hazards model. We study the sure screening property of the proposed method for independent and clustered survival data. The simulation study shows that the proposed method performs better for group variable screening than some existing procedures.

在比例风险模型中筛选组变量

我们提出了一种在比例风险模型的高维组变量设置下筛选组变量的方法。我们研究了所提出的方法对独立和聚类生存数据的确定筛选特性。仿真研究表明,所提出的方法在组变量筛选方面的性能优于现有的一些程序。
