The centroid scores Z1c, Z2c and individual scores Z1s, Z2s have been centered on Z0, which
is the midpoint or average of the centroids. From A, the weight or coefcient for the rst variable
is ten times the weight for the second variable, and the latter three to four times the weight of the
third. The F value is large enough that produces negligible p-value allowing us to reject the null,
indicating signicant difference between the two groups.
Using the individual scores and the centroid scores, the function also produces the plot of
Figure10.5, which displays the difference between the groups in two different manners. ...
