- The
relativevalue is the weighted sum of the differences with weight given by the inverse of the current value of the statistic. - The
absolutevalue is therelativevalue divided by the total sum of the inverses of the current values (i.e. the weighted average of the differences).

…onProd`, a union of products of subcomplexes (#37182) Given `X Y : SSet`, `S : X.Subcomplex`, and `T : Y.Subcomplex`, define the subcomplex `S.unionProd T : (X ⊗ Y).Subcomplex` given by `(X ⊗ T) ⊔ (S ⊗ Y)` and provide basic API. All code is originally written by Joël Riou and modified for PR to mathlib (with permission).
