3.2.2 Accuracy versus censor rate C. As common infections are typically under-reported, it is important to study how the estimation accuracy varies with censor rate. For a fixed network with N = 10,000 nodes and ,k. = 10, we simulated S = 100 SIRs and applied various censor rates C from 50% to 85%. The estimation accuracy is found to decrease as C increases (Figure 4a ). This is expected, as lower censor rate results in more data available for estimation and thus improves the accuracy.
