Web30 nov. 2016 · Among others, there exist three methods for detection and quantification of nestedness that are widely used: BINMATNEST, NODF, and FCM. However, these methods fail in detecting nestedness for graphs with low (NODF) and high (NODF, BINMATNEST) density or are developed for bipartite networks (FCM).
