Table 2.

Summary of the numerical results for the longer cut-off times. Here, the values of T are 9 for θ₁, 6 for θ₂ and 7 for θ₃ such that T is near the end of the epidemic process (also see figure 8). Method 3 yields accurate estimates without requiring knowledge of the size of the susceptible population n. Values in italics indicate the results corresponding to the best performing method.
