FILL BLANKSIn reference to the article ‘Data Mining for Fun and Profit’, Predictive models are important in ___________where often one is concerned with the possibility of manipulating practices so as to _____________. In general, of the customer base, _____________ of them followed the transaction. However, we were able to identify a subgroup of _______ of the customer base that had _________chance of exhibiting the transaction pattern.

ANSWER:In reference to the article ‘Data Mining for Fun and Profit’, Predictive models are important in commercial applications where often one is concerned with the possibility of manipulating practices so as to increase sales. In general, of the customer base, 12.5% of them followed the transaction. However, we were able to identify a subgroup of 10% of the customer base that had 43% chance of exhibiting the transaction pattern. Works CitedAbouRizk, Simaan.
