 3 observations per cluster within the median distance between
  all observations. If the number of clusters is = 0 means that there are at
  least 3 unique locations but observations are too spread and no cluster was
  found. If the number of unique locations is less than 3, observations are
  considered as a single cluster without outliers.</p></li>
<li><p>&#8220;nOutliers&#8221;: the number of observations whose distance to any
  cluster is beyond the median distance between all observations.</p></li>
