Specific comments. The applied methodology of clustering the hospital
wards and ICUs using the calculated multi-resistance is similar to the
analysis of variance (ANOVA) "in reverse." In particular, we
started with k random clusters, and then move cases (i.e. hospitals) between
those clusters with the goal to:
