    • 58% say they are adding to the knowledge base in the field.
    • 60% of respondents say the results of their modeling are deployed always or most of the time.
  • Most data miners feel that the economy will not negatively impact them.

    • SAS Enterprise Miner dropped in data miner’s tool rankings this year.
  • Users of IBM SPSS Modeler, Statistica, and Rapid Miner are the most satisfied with their software.
