    Although COMPLEXITY_PENALTY is documented in BOL as a parameter for the
    Time Series algorithm, it doesn't seem to be supported.



    [Execute SQL Task] Error: Executing the query "CREATE MINING MODEL
    SessionSalesForecast ( week_key LONG KEY TIME, product_key LONG KEY,
    sales_qty LONG CONTINUOUS PREDICT_ONLY) Using Microsoft_Time_Series
    (MISSING_VALUE_SUBSTITUTION = '0', MINIMUM_SUPPORT='24',
    COMPLEXITY_PENALTY='0.5');" failed with the following error: "Error
    (Data mining): The 'COMPLEXITY_PENALTY' data mining parameter is not
    valid for the 'SessionSalesForecast' model.



    Is the BOL wrong, or am I missing something?

    Elmer,

    COMPLEXITY_PENALTY parameter works in Enterprise Edition only.
