Cluster 1 details.

the attribute histograms and the rule of Cluster 1. Users can visually

inspect the attribute value distributions in each cluster to understand

how they differ. In this case Cluster 1 can be described as
customers

whose age is between 15 and 31.5 and whose income is between $5,000 and

$67,500.

Apply Clustering Model: Assign New Cases to the Clusters

A clustering model can be applied to the original cases or new cases

to assign each case a cluster ID. Clustering apply also computes the

probability that the case belongs to the cluster, and the distance of the

case from the centroid of the cluster to assess how well each case fits

a given cluster. Like classification, JDM supports assigning the top

cluster, mapping the top or bottom clusters for each case, and per

cluster probabilities.
