Abstract:

Multivariate data may be explored by a variety of methods. This paper considers some examples of alternative analyses by biplot display and by Tukeys 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
