The data is the results of a chemical analysis of wines grown in the same
|
||
|
|
region in Italy by three different cultivators. There are thirteen different
|
||
|
|
measurements taken for different constituents found in the three types of
|
||
|
|
wine.

The data was used with many others for comparing various
|
||
|
|
classifiers. The classes are separable, though only RDA
|
||
|
|
has achieved 100% correct classification.
