Figure 10.3
Ordinary PCA biplot of the flotation data with
X
=
U
V
. Samples are
plotted as
U
J
and variables are plotted in the form of calibrated axes where
VJ
gives
directions for the axes. Axis predictivities are given in parentheses. (Top) Variables not
normalized. (Bottom) Variables normalized to unit variances. We note some structure in
the data but do not pursue this further.
