In a Network Analysis What Connects Nodes?

a representation of a set of objects where some pairs of the objects are connected by links: Proteins (Nodes) with other Proteins (Nodes) via links (edges). ... a graph with n vertices in which each vertex is connected to each of the others (with one edge between each pair of vertices).

What are nodes and edges in network analysis?

Networks are composed of 2 elements, nodes and edges. Nodes represent the objects of interest, while the edges represent the connection between them. Nodes can be of the same or different category within a network graph.

What does network analysis include?

Network Analysis examines the structure of systems that are characterized by connections (or edges) between nodes [71]. A node can symbolize a range of objects, from individuals and species to patches in a landscape [72] whereas an edge signifies interactions between individuals or connectivity between patches.
