Table 2.

Statistical parameters for an edge pointing from a source node x to a target node y^a.

Parameter	Description	Formula
Absolute cooccurrence	Number of group members having both attributes of x and y	oi
Relative conditional share	Fraction of group members with attribute of x, also having attribute of y
Conditional and unconditional target share difference	Absolute increase of relative conditional share compared to relative attribute share of y
Conditional and unconditional target share quotient	Quotient of relative conditional share and relative attribute share of y

^aSubscript i refers to a definition for both groups. Let be the absolute count of x and be the relative attribute share of y.
