This question is more about learning statistics than about statistics per se, so please suggest another forum if this one is not appropriate.

I found this textbook (ISLR by James, Witten, Hastie, and Tibshirani) online and it seems like a great resource. I read a few chapters and then realized that I wasn't getting good comprehension. So now I've decided to answer the questions at the end of each chapter and write them up in LaTeX/knitr. I'm through chapter 3.

It would be amazing to discuss the solutions with other people who are using the same book. Maybe I'm getting them all wrong! Can anyone suggest a resource/forum/website where such a discussion might take place?

Stanford online course, which is archived here.

There are a few resources online for solutions:

A Solution Manual and Notes for ISLR by some MIT grad students (Weatherwax and Epstien) the posted a PDF easily found online (I would add PDF link but StackExchange won't let me add more than 2 links currently)



The 2nd link is someone's website. You could post questions on there and try to start a conversation. However a better solution would be PhysicsForums' website. I have had success posting data sci related problems there. They do a bunch of QA with homework type help and they usually have great and detailed discussions. They have a huge math/stats section with many experts willing to help.
