Informative Tuples Selected by the Shadow Algorithm When Applied to Example 1 (See Box 3 and Box 7 with K=3 and K=4)

Pair	MI	Triplet		Quadruplet
〈X17, X19〉	0.10945	〈X12, X17, X19〉	−0.07303	〈X11, X12, X17, X19〉	0.91699
〈X12, X19〉	0.07967	〈X11, X12, X19〉	−0.05766	〈X1, X11, X17, X19〉	0.283e-6
〈X11, X19〉	0.03758	〈X11, X17, X19〉	−0.03558	〈X4, X11, X17, X19〉	0.257e-6
〈X1, X4〉	0.00357	〈X1, X12, X19〉	−0.397e-5	〈X4, X11, X12, X19〉	0.248e-6
		〈X1, X17, X19〉	−0.362e-5	〈X4, X12, X17, X19〉	0.239e-6
		〈X4, X17, X19〉	−0.319e-5

In red are tuples that are either informative shadows (components of the dependency) or the dependency itself.
