Epidemiological statistics estimated from the raccoon rabies virus data set. a Time-series of the spatial distance between epidemic origin and maximal epidemic wavefront, and b evolution of the patristic distance between epidemic origin and maximal epidemic wavefront, c kernel density estimates of lineage velocity parameters and d kernel density estimates of lineage diffusion coefficient parameters (coefficient of variation “CV” against mean values). In parts a and b the grey area corresponds to the 95 % credible region of the estimated wavefront position. In parts c and d the three contours show, in shades of decreasing darkness, the 25 %, 50 %, and 75 % highest posterior density regions via kernel density estimation
