Extracts the Backbone from Weighted Graphs

Provides methods for extracting from a weighted graph a binary or signed backbone that retains only the significant edges. The user may input a weighted graph, or a bipartite graph from which a weighted graph is first constructed via projection. Backbone extraction methods include the stochastic degree sequence model (SDSM; Neal, Z. P. (2014). ), the fixed degree sequence model (FDSM; Zweig, K. A., and Kaufmann, M. (2011). ), the fixed row model (FRM; Neal, Z. P. (2013). ), the fixed column model (FCM; Neal, Domagalski, and Sagan (2021). ), the fixed fill model (FFM; Neal, Domagalski, and Sagan (2021). ), and a universal threshold method.
