A scalable and flexible Cox proportional hazards model for high-dimensional survival prediction and functional selection

  title={A scalable and flexible Cox proportional hazards model for high-dimensional survival prediction and functional selection},
  author={Boyi Guo and Nengjun Yi},
Cox proportional hazards model is one of the most popular models in biomedical data analysis. There have been continuing efforts to improve the flexibility of such models for complex signal detection, for example, via additive functions. Nevertheless, the task to extend Cox additive models to accomodate high-dimensional data is nontrivial. When estimating additive functions, commonly used group sparse regularization may introduce excess smoothing shrinkage on additive functions, damaging…

An additive Cox proportional hazards model is developed, in which each additive function is obtained by trend filtering, so that the fitted functions are piece-wise polynomial with adaptively-chosen knots.
The spike‐and‐slab lasso Cox model for survival prediction and associated genes detection
This work proposes new Bayesian hierarchical Cox proportional hazards models, called the spike‐and‐slab lasso Cox, for predicting survival outcomes and detecting associated genes and develops an efficient algorithm to fit the proposed models by incorporating Expectation‐Maximization steps into the extremely fast cyclic coordinate descent algorithm.

Variable Selection for Cox's proportional Hazards Model and Frailty Model
A class of variable selection procedures for parametric models via nonconcave penalized likelihood was proposed in Fan and Li (2001a). It has been shown there that the resulting procedures perform as

The additive hazards regression model relates the conditional hazard function of the failure time linearly to the covariates. This formulation complements the familiar proportional hazards model in
Model selection in nonparametric hazard regression
We propose a novel model selection method for a nonparametric extension of the Cox proportional hazard model, in the framework of smoothing splines ANOVA models. The method automates the model
