In the era of biomedical big data, survival outcome data with high-throughput predictors are routinely collected. These high dimensional data defy classical survival regression models, which are either infeasible to fit or likely to incur low predictability because of overfitting. This short course will introduce the basic concepts of survival analysis and various cutting-edge methods that handle survival outcome data with high dimensional predictors. I will cover statistical principles and concepts behind the methods, and will also discuss their applications to the real medical examples.
The topics include
Survival analysis overview: basic concepts and models, e.g.
i) Cox Models,
ii) Accelerated Failure Time (AFT),
and iii) Censored Quantile Regression (CQR) Models;
Survival models with high dimensional predictors (p>n): Regularized methods and Dantzig selector.
