# momepy.mean_node_degree¶

momepy.mean_node_degree(graph, radius=5, name='mean_nd', degree='degree', distance=None)[source]

Calculates mean node degree for subgraph around each node if radius is set, or for whole graph, if radius=None.

Subgraph is generated around each node within set radius. If distance=None, radius will define topological distance, otherwise it uses values in distance attribute.

Parameters
graphnetworkx.Graph

Graph representing street network. Ideally generated from GeoDataFrame using momepy.gdf_to_nx()

radius defining the extent of subgraph

namestr, optional

calculated attribute name

degreestr

name of attribute of node degree (momepy.node_degree())

distancestr, optional

Use specified edge data key as distance. For example, setting distance=’weight’ will use the edge weight to measure the distance from the node n.

Returns
Graph

mean node degree for graph if radius=None
>>> network_graph = mm.mean_node_degree(network_graph, radius=3)
