Introduction Motivation:
Need to create similar business model for stores with either similar product sales or customer GBB brand preference.
And explain these clusters in terms of demographic variables.
Challenges: Business rule requires that the store cluster size has
to be greater than certain number. Enforce a minimum cluster size with proc cluster.
Explore the relationship between the clusters and demographic variables.

Each observation begins in a cluster by itself. The two closest clusters are merged to form a new cluster.
Using Proc cluster to get the tree.
Using Proc tree to get the desired cluster.

Solution
Get the history of the clustering process using ODS.
ods output ClusterHistory=history;
proc cluster data=indatatemp METHOD=ward outtree=Tree;
Search clusters which satisfy the minimum size criteria from top to bottom.

Classify autozone stores based on market share of 2 oil brands, high mileage and blends.
Business rule requires minimum cluster size is 300.

Even borders. 1. Find centers of each cluster.
2. Calculate distance between store and each cluster center.
3. Reassign store to the closest cluster .
