4.1.1. Complete seasons
The basic tree produced by MC4 when looking at the
general model data for the 1995/1996 season is a fairly
simple tree using only 6 of the available 30 attributes, the
players Dozzell, Campbell, and Nethercott, the venue and
the opposing team ranking. The tree, Fig. 2, shows Dozzell
as a key player3. For the 1995/1996 season the MC4
analysis gives a reduction in the classiWcation error of
34.57% and 23.68% for the general and expert models,
respectively.
