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:
