  1. If you look at the comments in the blog you linked from, you can see that it appears as if the authors screwed up the stats. Wouldn't surprise me, just looking at that graph. No confidence intervals, no real data under those model curves, plotting an ordinal scale as if it were scalar, cropping the y axis at .1 instead of at 0. Anyone making that many rookie mistakes won't be properly analyzing a multiple regression model.
