Some Comparisons of Biplot Display and Pencil-and-Paper E.D.A. Methods. Revision.

Abstract

Multivariate data may be explored by a variety of methods. This paper considers some examples of alternative analyses by biplot display and by Tukey's pencil-and-paper EDA methods. It suggests that in using the biplot, a few displays usually suffice to reveal patterns in a pretty striking manner. When using EDA, on the other hand, one may require several stages of median polish, inspection of residuals, modelling, and re-expression. The biplot is more immediate: It allows one to see things at a glance. (Author)
