White wine quality data for data mining
Description
These data concern white variants of the Portuguese "Vinho Verde" wine.
Quality is an ordinal variable based on the median assessment of
of at least 3 wine experts. Each expert graded wine quality between 0 (very bad) and 10 (excellent).
Usage
data("wine")
Format
A data frame with 4898 observations on the following 12 variables.
YWine quality.
X1Volatile acidity.
X2Citric acid content.
X3Residual Sugar content.
X4Chloride content.
X5Free sulfur dioxide content.
X6Total sulfur dioxide content.
X7Density.
X8pH: -\log_{10} [H^{+}].
X9Sulphate content.
X10Alcohol content.
X11Fixed acidity.
