The readings below are for the next two weeks. They bridge between material on eigenvectors and an introduction to ideas of
regression
Green & Carroll,
Chapter 5
(eigenvalues): This is a fairly long chapter,
with a good deal of material rather more difficult
than I'd like. Focus on the following sections (&
see Stevens, for a brief summary): 5.1-5.2.2,
5.2.5-5.4.1, 5.5-5.6.4.
Some Java applets that allow you to visually explore
the properties of eigenvectors and eigenvalues of 2x2 and
3x3 matrices. Go to Eigenvalues and Eigenvectors.
