MeanNeighborDegree
gives a list of mean neighbor degrees of vertices for the graph g.
MeanNeighborDegree[g,"In"]
gives a list of mean neighbor in-degrees.
MeanNeighborDegree[g,"Out"]
gives a list of mean neighbor out-degrees.
MeanNeighborDegree[{vw,…},…]
uses rules vw to specify the graph g.
Details
- The mean neighbor degree is also known as the average neighbor degree.
- The mean neighbor degree of the vertex is the mean of vertex degrees of neighbors of .
- For weighted graphs, the mean neighbor degree of the vertex is given by over all neighbors of with edge weight between and . is the degree of the vertex and is the total of weights .
- MeanNeighborDegree works with undirected graphs, directed graphs, weighted graphs, multigraphs, and mixed graphs.
