4. Relevant Information:

   This file concerns credit card applications. All attribute names and values have been changed to meaningless symbols to protect confidentiality of the data.

   This dataset is interesting because there is a good mix of attributes -- continuous, nominal with small numbers of values, and nominal with larger numbers of values. There are also a few missing values.

5. Number of Instances: 690

6. Number of Attributes: 15 + class attribute
