The course looks at the theoretical and practical implications of a wide array of clustering techniques that are currently available in SAS. The techniques considered include cluster preprocessing, variable clustering, k-means clustering, and hierarchical clustering.

• Prepare and explore data for a cluster analysis.
• Distinguish among many different clustering techniques, making informed choices about which to use.
• Evaluate the results of a cluster analysis.
• Determine the appropriate number of clusters to retain.
• Profile and describe clustered observations.
• Score observations into clusters.
