An overview of variable selection in multiple regression
This repository contains a series of R notebooks I developed to illustrate some basic principles of variable selection in multiple regression. I make no claim to be an expert. I am simply sharing what I understand about the principles. You'll need to have RStudio installed to take full advantage of the R notebook features, but the open source version of RStudio has served my needs well,1 it will only cost you a little disk space.
I've been using editors long enough, though, that I only use the editor in RStudio when I'm editing an R notebook. Otherwise, Emacs (https://www.gnu.org/software/emacs/emacs.html) is my editor of choice.
