PluMA plugin to take a signed, weighted network and output the number of stable and unstable triads, a useful metric for social network research (Easley, 2010).
This plugin expects input in CSV format, where rows and columns each correspond to nodes and entries in the matrix to edges; for example A(i, j) would be the weight of the edge from node i to node j. A weight of zero means no edge.
Stable social networks have triads that are all stable, meaning that the number of positive edges is odd (either 3 or 1). This implies that in stable social networks, nodes with common friends or enemies should be also friends (not enemies).
