Figure 3. — The effect on estimates of the growth parameter, r, in an exponential coalescent when considering (a) clusters, (b) random subtrees, and (c) tips dropped at random. Colours represent the number of tips in the tree: yellow = 200, green = 400, pink = 600, and purple = 800. The blue region shows the 2.5 and 97.5% points of the bias in the randomly dropped tips trees for comparison. The bar plots show the proportion of phylogenies favouring the constant versus exponential (middle column) or constant versus exponential and logistic models (rightmost column) for the standard (light grey) and censored (dark grey) likelihoods.
