|SNA methods provide specific mathematical definitions of five groups of characteristics of the actors/ nodes and of the network itself (Bonacich, P., 1987; Burt, R. S., 1992):
2. equivalence (role-groups),
3. power of actors,
4. range of influence, and
These characteristics are expressed in terms of corresponding network structure parameters derived from the relations among actors. There is vast amount of material is available for the introduction to SNA which can be easily, for example, in (Scott, J., 2000; Hanneman, R. E., 2005; Wasserman, S., Faust, K., 1994). The insights that can be obtained from the various values of the
network structures are elaborated in Burt (1990)
|SNA methods provide precise mathematical definitions of five groups of characteristics of the actors and of the network itself [EN 18, EN 19]: cohesion, equivalence (role-groups), power of actors, range of influence, and brokerage. These characteristics are expressed in terms of corresponding Network-Structure parameters derived from the relations among the actors. An introduction to SNA can be found in Scott  and Hanneman . For a comprehensive text, see Wasserman and Faust . Burt  elaborates on the insights that can be obtained from the various values of the network structures.
