%    The data was used with many others for comparing various 
%    classifiers. The classes are separable, though only RDA 
%    has achieved 100% correct classification.
%    (RDA : 100%, QDA 99.4%, LDA 98.9%, 1NN 96.1% (z-transformed data))
%    (All results using the leave-one-out technique)
% 
%    In a classification context, this is a well posed problem 
%    with "well behaved" class structures. A good data set 
%    for first testing of a new classifier, but not very 
%    challenging.

% 
%    Here, the data was used to illustrate the superior performance of
%    the use of a new appreciation function with RDA.

% 4. Relevant Information:
% 
%    -- These data are the results of a chemical analysis of
%       wines grown in the same region in Italy but derived from three
%       different cultivars.
%       The analysis determined the quantities of 13 constituents
%       found in each of the three types of wines. 
% 
%    -- I think that the initial data set had around 30 variables, but 
%       for some reason I only have the 13 dimensional version. 
%       I had a list of what the 30 or so variables were, but a.) 
%       I lost it, and b.), I would not know which 13 variables
%       are included in the set.
% 
%    -- The attributes are (dontated by Riccardo Leardi, 
% 	riclea@anchem.unige.it )
%  	1) Alcohol
%  	2) Malic acid
%  	3) Ash
% 	4) Alcalinity of ash  
%  	5) Magnesium
% 	6) Total phenols
%  	7) Flavanoids
%  	8) Nonflavanoid phenols
%  	9) Proanthocyanins
% 	10)Color intensity
%  	11)Hue
%  	12)OD280/OD315 of diluted wines
%  	13)Proline            
% 
% 5. Number of Instances

% 	13
% 
% 7. For Each Attribute:
% 
% 	All attributes are continuous
% 	
% 	No statistics available, but suggest to standardise
% 	variables for certain uses (e.g. for us with classifiers
% 	which are NOT scale invariant)
% 
% 	NOTE: 1st attribute is class identifier (1-3)
% 
% 8. Missing Attribute Values:
% 
% 	None
