The territorial map helps you to study the relationships between
the groups and the discriminant functions. Combined with the structure matrix results,
it gives a graphical interpretation of the relationship between predictors and
groups.
The first function,
shown on the horizontal axis, separates group 4
(Total service customers)
from the others. Since Level of education is
strongly positively correlated with the first function, this suggests that your
Total service customers
are, in general, the most highly educated.
The second function separates groups 1 and 3
(Basic service and
Plus service customers).
Plus service customers
tend to have been working longer and are older than
Basic service customers.
E-service customers are
not separated well from the others, although the map suggests that
the tend to be well educated with a moderate amount of work
experience.
In general, the closeness of the group centroids, marked
with asterisks (*), to the
territorial lines suggests that the separation between
all groups is not very strong.
Only the first two discriminant functions are plotted, but
since the third function was found to be rather insignificant,
the territorial map offers a comprehensive view of the
discriminant model.
