Bipartite Random Graph for Python

The Bipartite Random Graph (BiRG) is a statistical null model for binary bipartite networks. It offers an unbiased method of analyzing node similarities and obtaining statistically validated monopartite projections [Saracco2016].

The BiRG is an extension of the Erdős–Rényi model [ER] to bipartite graphs. Link probabilities are obtained by constraining the total number of links between the two layers in the network. Similar null-models, which are based on the principle of entropy maximization, are

• BiCM - Bipartite Configuration Model
• BiPCM - Bipartite Partial Configuration Model

Please consult the original articles for details about the underlying methods and applications to user-movie and international trade databases [Saracco2016, Straka2016].
