Validation results. k-EMD was tested on a dataset, that includes 34 out- breaks; MinDist, ReD and VOICE were validated earlier on a smaller dataset, that didn’t include one of the outbreaks. For convenience, results for k-EMD contain 2 values - one for the smaller dataset, and one for the entire (34 outbreaks) set of hosts (values in parentheses)
