NW_PROJECTION: Stata module to project a bipartite network into one of its two dimensions

Charlie Joyez

Statistical Software Components from Boston College Department of Economics

Abstract: A bipartite network is made of two sets of nodes (X and Y) where only connections between nodes in different sets are allowed. From an edgelist of a bipartite network, nw_projection returns the resulting projection into one dimension (Zhou et al., 2007, Phys. Rev. E). A projection consists in liking two nodes in the same set X according to the number of neighboring Y nodes. The projection reduces the network into a unimodular one where remaining X nodes are identified in the X(varlist). The Y nodes must be identified in Y(varlist). nw_projection returns etiher the adjacency matrix of the projected network, or its edgelist, and the former dataset is deleted. The adjacency matrix is also stored as a Mata matrix, and as a network.
