Title:   Marginal screening and post-selection inference

Abstract:
This talk discusses marginal screening for detecting the presence of  
significant predictors in high-dimensional regression.  Screening  
large numbers of predictors for the presence of a significant  
association with response is a challenging problem.  The difficulty is  
due to the non-regular behavior of the maximal sample correlation at  
the null hypothesis of interest in marginal screening.  To address  
this problem, we propose a bootstrap approach that adapts to the  
non-regularity.  The proposed approach provides a more powerful  
alternative to the popular (yet conservative) Bonferroni method of  
controlling familywise error rates in this setting.  Two applications  
are discussed: 1) gene expression associated with the survival time of  
brain cancer patients, and 2) HIV mutations associated with ARV drug  
resistance.

A palestra será no auditório Antonio Gilioli no blco A
