Continuing the playlist on Regression, I have uploaded a new video to YouTube: Regression Part 3: Analysis Basics. It talks about things that are required for all 3 types of Regression covered in the book -- Simple Linear, Multiple Linear, and Simple Nonlinear Regression. Topics include clip levels for R squared, Residuals, establishing Cause and Effect, and the dangers of Extrapolation. See the videos page of this website for the status of completed and planned videos.
