The next step is to verify that these cluster groups are distinct from each other by
using the decision tree technique.
4.6 Decision tree analysis
In this study the decision tree is obtained using the regression tree since all the data are
continuous. The objective of doing decision tree is to verify whether the cluster groups
are classified properly and the profile of the clusters can be easily and accurately
