- 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).

…gory is a transfinite composition of pushouts of monomorphisms in a small family (#22157) Let `C` be a Grothendieck abelian category. Assume that `G : C` is a generator of `C`. Then, any morphism in `C` is a transfinite composition of pushouts of morphisms of the form `Y ⟶ G` for some subobject `Y` of `G`. Co-authored-by: Joël Riou <[email protected]>

* polynomial-sequences: (558 commits) Correct the TODO to mention IsCancelAdd which does exist. Talk about strict monotonicity instead, thanks @pechersky. Mention the TODO on li generalization to semirings. One more dedent. Same injectivity twiddling for basis. nontiviality to simplify this proof, and some dedenting. Hopefully more correct injectivity lemmas matching the naming convention. Fix the empty docstring. Update Mathlib/Algebra/Polynomial/Sequence.lean Fix the variable naming.
