How is reciprocity calculated?

In calculated reciprocity, the exchange is intentional, transferred resources or services have a known value, partners keep track of exchanges over time, they understand present costs and future benefits of each altruistic interaction and expect the same or other resources or services to be returned (de Waal and …

How do you find the reciprocity of a graph?

Compute the reciprocity in a directed graph. The reciprocity of a directed graph is defined as the ratio of the number of edges pointing in both directions to the total number of edges in the graph. Formally, r = | ( u , v ) ∈ G | ( v , u ) ∈ G | / | ( u , v ) ∈ G | .

What does network density mean?

In social network analysis, the term network density refers to a measure of the prevalence of dyadic linkage or direct tie within a social network. A social network can be defined as a network formed by a set of interacting social entities (actors) and the linkages (relations or edges) among them.

What is clustering coefficient in networks?

In graph theory, a clustering coefficient is a measure of the degree to which nodes in a graph tend to cluster together. The global version was designed to give an overall indication of the clustering in the network, whereas the local gives an indication of the embeddedness of single nodes.

What is entropy in network science?

In network science, the network entropy is a disorder measure derived from information theory to describe the level of randomness and the amount of information encoded in a graph. It is a relevant metric to quantitatively characterize real complex networks and can also be used to quantify network complexity.

How do I interpret my EI index?

The E-I (external – internal) index takes the number of ties of group members to outsiders, subtracts the number of ties to other group members, and divides by the total number of ties. The resulting index ranges from -1 (all ties are internal to the group) to +1 (all ties are external to the group).

What is a triad in a network?

A basic element of social network theory and analysis is the dyad, or pair of actors who may or may not share a social relation with one another. A triad is a set of three actors, which also consists of three dyads.

What is a dyad network?

The dyad, the simplest multiple actor network, is a link between two actors. In the analysis of dyads, only the characteristics of the relationship form the structural effects on outcomes. A second effect is possible where each dyad is influenced by the triad itself.

What is ego network?

Ego Network Egocentric networks are local networks with one central node, known as the ego. The network is based off the ego and all other nodes directly connected to the ego are called alters. An Ego is the focal point of the network during data collection and analysis and are ‘surrounded’ by alters.

What is Edge density?

Description. ED equals the sum of the lengths (m) of all edge segments in the landscape, divided by the total landscape area (m2), multiplied by 10,000 (to convert to hectares).

What is Neighborhood overlap?

Abstract. The neighborhood overlap (NOVER) of an edge u-v is defined as the ratio of the number of nodes who are neighbors for both u and v to that of the number of nodes who are neighbors of at least u or v.

What is AVG in networking?

Average path length is a concept in network topology that is defined as the average number of steps along the shortest paths for all possible pairs of network nodes. It is a measure of the efficiency of information or mass transport on a network.
