Scagnostics

Scagnostics (scatterplot diagnostics) is a series of measures that characterize certain properties of a point cloud in a scatter plot. The term and idea was coined by John Tukey and Paul Tukey, though they didn't publish it; later it was elaborated by Wilkinson, Anand, and Grossman. The following nine dimensions are considered:


 * 1) For the outliers in the data:
 * 2) outlying
 * 3) For the density of data points:
 * 4) skewed
 * 5) clumpy
 * 6) sparse
 * 7) striated
 * 8) For the shape of the point cloud:
 * 9) convex
 * 10) skinny
 * 11) stringy
 * 12) For trends in the data:
 * 13) monotony
