Edge-based compartmental modelling for configuration model (CM) networks. The flow diagram for a static CM network. (a) The ϕS, ϕI and ϕR compartments represent the probability that a partner is susceptible, infected or recovered and has not transmitted infection. The 1 − θ compartment is the probability that it has transmitted. The fluxes between the ϕ compartments result from infection or recovery of a partner of the test node and the ϕI to 1 − θ flux results from a partner transmitting infection to the test node. (b) S, I and R represent the proportion of the population susceptible, infected and recovered. We can find S explicitly, and I and R follow as in the mass action model. (Online version in colour.)
