- 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).

* polynomial-sequences: (149 commits) Aha, here's how to get Lean to stop showing S.elems' in the infoview. Try satisfying the linter gods again. Probably enough initial tidying to send the PR. Kill more temporary names. Touch more natDegree. Does protected satisfy the docstring linter? Bit shorter. More Quiet linters. Remove redundant imports. Copyright header and more twiddling.
