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 they 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.
