Figure 2.

Example of output graphics for a 454 sample that conformed to the model. Pairwise HD frequency plots on a logarithmic scale (black, left panel), together with the best fitting Poisson (blue) and the theoretical counts expected if the sample were to follow a star-like phylogeny. The right panel shows the pairwise HD histogram and the best fitting Poisson distribution (red). In the legend we report the GOF P-value (P = 0.981), the estimated days since the infections (d = 34(31, 38)), and the number of sequences in the sample (N = 4046).
