Dartmouth Area SAS Users Group Meeting (Virtual via Zoom)
Date/Time: July 28, Thursday, 11:00 AM – 13:00 PM EST.
1. Title: Introduction to Penalized Regression and Variable Selection Methods in SAS/STAT® and SAS® Viya® Procedures
Abstract:
Variable selection is a fundamental task in high-dimensional modeling and statistical learning. A sparse model that is composed of a subset of variables is usually preferable to a full model that uses all input variables because of its better interpretability and higher prediction accuracy. Traditional approaches such as stepwise regression use sequential procedures, which are computationally intensive and unstable. Alternative selection methods use sparsity inducing penalized regression techniques to simultaneously select variables and estimate regression coefficients. In this talk, I will review the variable selection methods in linear regression, and present practical examples using SAS/STAT and SAS Viya procedures.
Bio of the speaker:
Yingwei Wang is a Sr. Research Statistician Developer at Advanced Analytics Division of SAS. He specializes in variable selection methods in linear models and support the GLMSELECT and REGSELECT procedures in SAS. Yingwei got his PhD from the Department of Mathematics at Purdue University.
2. Title: Version Control With SAS® and Git
Abstract:
Few technologies have done more to advance code collaboration and automation than Git. GitHub's popularity has drawn the attention of all types of programmers including SAS programmers. Many SAS products have direct integration with Git –extending to GitHub. In this session we will cover the following: • What is Git and why do I care? • Using Git with SAS Enterprise Guide. • Using Git with SAS Studio. • Git functions in Base SAS. • Where to learn more.
Bio of the speaker:
Chris Hemedinger leads SAS Communities & User Groups, where SAS users gather to share questions, answers, and best practices. Since 1993, Chris has worked for SAS as an author, a software developer, an R&D manager, and a consultant.
