  • 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).

What is the plan for categories with more than one canonical model structure? Have wrappers with the respective instances?

What is the plan for categories with more than one canonical model structure? Have wrappers with the respective instances?
