  • 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 am a bit confused by the name of the theorem just above this new one:

Perhaps renaming it in a different pull request might be a good idea?
