Inference of Transmission Network Structure from HIV Phylogenetic Trees

Mean branch length as function of the number of taxa varying sampling fraction.
Mean branch length as function of sampled hosts, with varying sampling fraction (p = 1-0.25). The envelopes represent 95% confidence intervals around the medians. The curves are obtained using local regression (LOESS). Note that for smaller sampling fractions the envelopes include fewer taxa. WS (red), ER (green), BA (blue).
