spaeth2_06.txt, a sample data set
of 23 12D points, representing the monthly values of 23 seasonal
quantities.

spaeth2_07.txt, for each of 89
Bavarian postal codes, the area, population, and population density.

spaeth2_08.txt, for each of 89
Bavarian postal codes, the number of workers in 4 categories.

spaeth2_09.txt, a "distance"
matrix representing the perceived pairwise distance between
11 car models.

spaeth2_10.txt, a "distance"
matrix representing the rank ordering of 15 breakfasts.

spaeth2_11.txt, the values of 5 socioeconomic variables in 12 municipalities.

spaeth2_12.txt, a 4 by 4 matrix
of 0's and 1's, which is to be symmetrically permuted so that
the 1's form blocks.

spaeth2_13.txt, a 27 by 27 matrix
of 0's, 1's, 2's and 3's, which is to be symmetrically permuted
so equal numbers form blocks as far as possible.
