The data can be used to test (ordinal) regression or classification (in effect, this is a multi-class task, where
the clases are ordered) methods. Other research issues are feature selection and outlier detection.
The data includes two datasets:

winequality-red.csv – red wine preference samples;

winequality-white.csv – white wine preference samples;

The datasets are available here: winequality.zip
