12.3.56 OrdinalAttributeProperties


   An OrdinalAttributeProperties object is used to describe properties of the ordinal attribute. Ordinal attributes can use the “ordered? constraint on the MiningCategory class to use the “asIs? OrderType. The “asIs? allows the list ordering to imply a “less than? relationship between categories N and N+1. In addition, ordinals may be cyclic (e.g., days of the week).
