Reciprocity
The reciprocity of a directed network reflects the proportion of edges that are symmetrical. That is, the proportion of outgoing edges that also have an incoming edge. It is commonly used to determine how inter-connected directed networks are. An example of a such a network may be grooming exchanges in chimpanzees. Certain chimps may groom another but do not get groomed by that individual, whereas other chimps may both groom each other and so would have a reciprocal tie.
