CHAPTER 4
Dimensions 1, 2, 3, . . . , ∞
In the previous chapters, we used numerical and graphical tools in parallel. The general idea is
that there is a strict correspondence. A graphical tool is only worth as much as the hard statistics
that is supporting it. If we go to higher dimensions, we have to review this correspondence.
Some of the problems with higher dimensions come from perception. It is doubtful that humans
are made for handling numbers. Even if we are numerate, most of us barely can go beyond one
dimension as far as numbers are concerned. We can display numbers in a table, generally with
a matrix layout. This gives us two dimensions
