Leonard A. Stefanski, PhD

Variable Selection and Measurement Error

Abstract: The talk will describe some creative uses of measurement error modeling concepts for the purpose motivating certain approaches to variable selection. The development from concept to method will be traced and methods so derived will be presented. Some previous work will be briefly reviewed and certain recent work more thoroughly described.

The talk will draw upon recent as yet unpublished work, and the published papers: Luo, Boos, and Stefanski (Technometrics 2006);  Wu, Boos, and Stefanski (JASA 2007); Stefanski,  Wu, and White (JASA 2014); and White, Stefanski, and Wu (JASA 2016); as well on.

Stefanski has coauthored three books, one edited volume, and numerous research arti- cles. His research, funded by the National Science Foundation and the National Institutes of Health, has been in the general area of statistical inference with particular emphasis on the analysis of data measured with error, robust statistical procedures, and variable and model selection. He has consulted extensively with environmental scientists at the US EPA (1981-2015).
