%    - Publications: too many to mention!!!  Here are a few.

"%       to Mathematical Statistics"" (John Wiley"	 NY	 1950).

%       conceptual clustering system finds 3 classes in the data.			
% 			
% 4. Relevant Information:			
%    --- This is perhaps the best known database to be found in the pattern			
%        recognition literature.  Fisher's paper is a classic in the field			
%        and is referenced frequently to this day.  (See Duda & Hart	 for		
%        example.)  The data set contains 3 classes of 50 instances each			
%        where each class refers to a type of iris plant.  One class is	
%        linearly separable from the other 2; the latter are NOT linearly	
%        separable from each other.	
%    --- Predicted attribute: class of iris plant.	
%    --- This is an exceedingly simple domain.	
% 	
% 5. Number of Instances: 150 (50 in each of three classes)	
% 	
% 6. Number of Attributes: 4 numeric	 predictive attributes and the class
% 	
% 7. Attribute Information:	
%    1. sepal length in cm	
%    2. sepal width in cm	
%    3. petal length in cm	
%    4. petal width in cm	
%    5. class: 	
%       -- Iris Setosa	
%       -- Iris Versicolour	
%       -- Iris Virginica	
% 	
% 8. Missing Attribute Values: None	
% 	
% Summary Statistics:	
%  	           Min  Max   Mean    SD   Class Correlation
%    sepal length: 4.3  7.9   5.84  0.83    0.7826
