Other character types
The classification of Hoyal Cuthill and Lloyd (in review) was derived as a means to delineate a mathematical problem. As such it may be of use to consider where some special kinds of character would fall in this classification.
Stratigraphic characters
These would be classified as either Type VI, Type VII, Type XI, or Type XII characters (depending on state count and spacing of stratigraphic units).
Gap-weighted characters
A gap-weighted (Thiele 1993) character would be classified as either Type II or Type IV (depending on state count), but differ in the implicit assumption of whether all states are expected to be sampled. For a gap-weighted character there is no presumption that every state be sampled as the spacing between states is the primary information being considered.
Continuous characters
Continuous characters are necessarily not classifiable here as they are by definition non-discrete (except where translated into a gap-weighted character, above).
Value
A text string indicating the classification result (e.g., "Type VIII").
