CHAPTER 1 - Biplots in Practice, by Michael Greenacre
Video 1.1
This video shows the scatterplot of the trivariate data from Exhibit 1.1, rotating the scatterplot around the
vertical dimension ("Purchasing power").
Video 1.2
This video shows the same trivariate data from Exhibit 1.1, rotating the scatterplot in a “diagonal” direction until the country points are as spread out as possible., where the video pauses. This shows that the points must lie approximately in a plane and this viewpoint is looking at that plane.
