Thank you for bringing up this book! Here at SAS, we've not officially addressed the questions in Introduction to Statistical Learning, but we'll definitely consider incorporating them into future publications. There's an analogous reference to statistical modeling in SAS/STAT. In this doc, you'll find lots of examples of these concepts.
Good news: We've extended SAS Hackathon registration until Sept. 12, so you still have time to be part of our biggest event yet – our five-year anniversary!
