Fig. 2From: Path-level interpretation of Gaussian graphical models using the pair-path subscoreThe three panels show the possible pairings of nodes in the simple case of a three node network, with \(\pi _{ij}\) denoting the partial correlation between nodes i and j. In each case, the marginal correlation between the nodes is proportional to the sum of the products of partial correlations along the two network paths connecting themBack to article page
