This chapter introduces positional analysis which is conducted by defining positions in a network and reducing a network to these positions and mapping the relations between positions. The chapter also covers individual measures of positions in which nodes are defined as occupy the same position based on their connections to others or the similarity in their distances to others in the network. These individual equivalence positions can be used to group people into positions and to model the ways in which network positions influence behavior. Positions are composed of people who seem to be in the same space in the network, regardless of whether they are directly connected to one another, though they might be.

Keywords:   network positions, roles, hierarchical, structural equivalence, image matrix
