Personal Loan

The marketing department of a financial firm keeps records on customers, including
demographic information and, number of type of accounts. When launching a new product, such
as a "Personal Equity Plan" (PEP), a direct mail piece, advertising the product, is sent to existing
customers, and a record kept as to whether that customer responded and bought the product.
Based on this store of prior experience, the managers decide to use data mining techniques to
build customer profile models.

Each record is a customer description where the "pep" field indicates whether or not that
customer bought a PEP after the last mailing.
