|4. Relevant Information Paragraph:
| There are 19 classes, only the first 15 of which have been used in prior
| work. The folklore seems to be that the last four classes are
| unjustified by the data since they have so few examples.
| There are 35 categorical attributes, some nominal and some ordered. The
| value ``dna'' means does not apply. The values for attributes are
| encoded numerically, with the first value encoded as ``0,'' the second as
| ``1,'' and so forth. An unknown values is encoded as ``-1.''
