Determine two-dimensional representations of the data in the painters data frame (MASS) using (1) classical metric scaling; (2) Sammon scaling; (3) Kruskal’s non-metric scaling. On each graph show the school to which the painter belonged.

Create a version of Figure 12.4B that shows the discriminant line. In the example of Subsection 12.2.1, investigate whether use of logpet, in addition to logwid and loglen, improves discrimination.
