     SAS Note: SN-003218
     Product: ENT MINER
     Component: CLUSTER

    Title:
    Results will be incorrect with certain clustering criteria

    Keywords:
    ENT MINER ENTERPRISE CLUSTER CLUSTERING INCORROUT INCORRSTAT FASTCLUS
    NODE

    If you specify 'Midrange', 'Mean Absolute Deviation (Median)', 'Newton'
    or 'Modified Ekblom-Newton' as the Clustering Criterion (on the Seeds
    tab), the score code generated by the Clustering Node will be incorrect.
    This means that observations will not be correctly assigned to clusters.
    If you use the Score Node to assign observations based on the scoring
    code generated by the Clustering Node, those results will not be correct
    either. You will not see any errors or warnings to let you know that
    there is a problem. To circumvent the problem, use either
    'Least Squares' or 'Lease Squares (Fast)' as the Clustering Criterion.
