  • The relative value is the weighted sum of the differences with weight given by the inverse of the current value of the statistic.
  • The absolute value is the relative value divided by the total sum of the inverses of the current values (i.e. the weighted average of the differences).

I'll split the file about uniformly doubling measures in Defs and Lemmas first. UPD: I've reduced imports of the file instead of splitting it.
