3.2.3 Accuracy versus number of SIR S. Incidence data from a single epidemic will not provide a good picture of the network, because of censorship and history dependence of the epidemic. For different seeds, the epidemic progresses along different transmission routes. Thus, even if we could track all incidences for a given epidemic we are seeing an incomplete snapshot of the infection network. With censorship, this snapshot is even more incomplete. This is why we need to accumulate information from successive epidemics to make consistent and reliable estimates of the network links that participate in the transmission. In Figure 4b , we show the estimation accuracy as a function of the number of different SIR epidemics S used in the estimation with 50% censor rate. We found the accuracy to improve with S initially before saturating to 100% as more incidence data becomes available. It thus appears that faithful estimation of the infection network is asymptotically possible.
