METHODOLOGICAL INFORMATION

1. Description of methods used for collection-generation of data:
format: tab-delimited text 

dataset characteristics: multivariate

atribute characteristis: real (Z-scores)

pretreatment: column autoscaling (substracting its mean and dividing by its standard deviation)

size: 128 x 7 

  128 samples of red young wines from Spanish DOC (Denominación de Origen Calificada) Rioja.
  First six columns: six variables related to physical-chemical measures of color:
		1. red/green chromaticity (a)
		2. yellow/blue chromaticity (b), 
		3. lightness (L), 
		4. chroma (C) 
		5. hue (H)
		6. saturation (S)
  Last column: Label given by expert tasters after visual inspection of color.

Data are autoscaled for confidentiality reasons.
