for i<j. Note that λij is chosen to ensure Pr(Yij0=1)+Pr(Yij1=1)=1. In this formulation, the expansiveness and attractiveness parameters were reduced to a single parameter, α, which represents the propensity of a gene to be connected in an undirected network. Hence, the p1-model seeks to find the probabilities of edge formation in a network considering its structural features explicitly.
