Figure 7.13
Two-dimensional CA biplot of the 2007/08 crime data set. The contingency
ratio is approximated by plotting
R

U
and
C

V
with correctly adjusted scales and
with the argument
lambda = TRUE
. Only biplot axis
DrgR
is shown with calibrations
in terms of 2

times the chi-squared distance matrix between the rows of the
2007/08 crime data set. The chi-squared distance is defined as the square root of
d
