Figure 5

GLM with a binary response variable. The curve depicts the predictions from the model for the selected well-performing GBDP settings (see main text). The y-axis indicates the GBDP-derived probability that a DDH value is above 70%, indicating that two genomes represent organisms of the same species. The orange vertical line marks the distance threshold for species delineation as provided by the GLM, i.e., denoting a probability of 0.5. The blue vertical line marks an alternative error ratio-based distance threshold as presented in our previous article [8].
