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). <10.1016>),
the fixed degree sequence model (FDSM; Zweig, K. A., and Kaufmann, M. (2011). <10.1007>),
the fixed row model (FRM; Neal, Z. P. (2013). <10.1007>),
the fixed column model (FCM; Neal, Domagalski, and Sagan (2021). <2105.13396>),
the fixed fill model (FFM; Neal, Domagalski, and Sagan (2021). <2105.13396>),
and a universal threshold method.2105.13396>2105.13396>10.1007>10.1007>10.1016>
