是UCI数据库中的一些有代表性的数据集

%                2 = slight
%                3 = significant
%           - a large gas cap in the stomach is likely to give the horse
%             discomfort
% 
%  15: nasogastric reflux
%           - possible values
%                1 = none
%                2 = > 1 liter
%                3 = < 1 liter
%           - the greater amount of reflux, the more likelihood that there is
%             some serious obstruction to the fluid passage from the rest of
%             the intestine
% 
%  16: nasogastric reflux PH
%           - linear
%           - scale is from 0 to 14 with 7 being neutral
%           - normal values are in the 3 to 4 range
% 
%  17: rectal examination - feces
%           - possible values
%                1 = normal
%                2 = increased
%                3 = decreased
%                4 = absent
%           - absent feces probably indicates an obstruction
% 
%  18: abdomen
%           - possible values
%                1 = normal
%                2 = other
%                3 = firm feces in the large intestine
%                4 = distended small intestine
%                5 = distended large intestine
%           - 3 is probably an obstruction caused by a mechanical impaction
%             and is normally treated medically
%           - 4 and 5 indicate a surgical lesion
% 
%  19: packed cell volume
%           - linear
%           - the # of red cells by volume in the blood
%           - normal range is 30 to 50. The level rises as the circulation
%             becomes compromised or as the animal becomes dehydrated.
% 
%  20: total protein
%           - linear
%           - normal values lie in the 6-7.5 (gms/dL) range
%           - the higher the value the greater the dehydration
% 
%  21: abdominocentesis appearance
%           - a needle is put in the horse's abdomen and fluid is obtained from
%             the abdominal cavity
%           - possible values:
%                1 = clear
%                2 = cloudy
%                3 = serosanguinous
%           - normal fluid is clear while cloudy or serosanguinous indicates
%             a compromised gut
% 
%  22: abdomcentesis total protein
%           - linear
%           - the higher the level of protein the more likely it is to have a
%             compromised gut. Values are in gms/dL
% 
%  23: outcome
%           - what eventually happened to the horse?
%           - possible values:
%                1 = lived
%                2 = died
%                3 = was euthanized
% 
%  24: surgical lesion?
%           - retrospectively, was the problem (lesion) surgical?
%           - all cases are either operated upon or autopsied so that
%             this value and the lesion type are always known
%           - possible values:
%                1 = Yes
%                2 = No
