Cluster Analysis

The tool Non-spatial clusters in the Spatial Data Calculator (SDC) provides necessary tools for these exercises. Alternatively, Statsoft Statistica installed to the computers in the room 202 can be used for such excercises. A cluster tree can be pruned at different levels. The number of clusters and the clusters depend on the pruning level.
