Gregory PS: An earlier posting of the book draft of Data Mining In Excel was so popular that it attracted the attention of the book authors, who sent the following reply via Janet Dobbins:
We are glad to see such interest in our book from the KDnuggets community. We were not aware of the (illegal) freely circulating "early draft" of our book. Although we love the viral effect, a comment about this version is in place:
This early draft is a significantly inferior version of the 1st edition of Data Mining for Business Intelligence, by Galit Shmueli, Nitin R. Patel, and Peter C. Bruce. The 2nd edition is a further significant improvement. Plus, the books contain a free 6-month license to XLMiner. We therefore strongly encourage those who like the flavor of the early draft to get hold of a copy of the book (or Kindle). Parts of the official editions can be viewed for free on Amazon Look-Inside.
Instructors interested in evaluating the book can get a free eval copy at http://dataminingbook.com/order-eval-copy
Please join the book Facebook group - we'd love to get your inputs.
