• 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).

🚨 PR Title Needs Formatting

Please update the title to match our commit style conventions.

Errors from script:

error: the PR title should be of the form
  abbrev: main title
or
  abbrev(scope): main title

Details on the required title format

The title should fit the following format:

<kind>(<optional-scope>): <subject>

<kind> is:

• feat (feature)
• fix (bug fix)
• doc (documentation)
• style (formatting, missing semicolons, ...)
• refactor
• test (when adding missing tests)
• chore (maintain)
• perf (performance improvement, optimization, ...)
• ci (changes to continuous integration, repo automation, ...)

<optional-scope> is a name of module or a directory which contains changed modules.
This is not necessary to include, but may be useful if the <subject> is insufficient.
The Mathlib directory prefix is always omitted.
For instance, it could be

• Data/Nat/Basic
• Algebra/Group/Defs
• Topology/Constructions

<subject> has the following constraints:

• do not capitalize the first letter
• no dot(.) at the end
• use imperative, present tense: "change" not "changed" nor "changes"

Hi! Thanks for your contribution. Can you elaborate more on this PR? What does it define? (I gather it defines "anti-Pascal triangles"... please say so, and tell us what these are. Right now, I have to guess, which does not suffice.) What is your motivation for defining these?

I have only seen references to this concept in the third problem of the IMO 2018. If this is your only motivation, this definition should be localised to a file providing the proof of that IMO problem.

Okay, I will add the comments and put them in the IMO proof problem file, thank you.

we are working on an applied mathematics problem that required defining anti-Pascal triangles. I found it quite interesting, so I thought I'd try to contribute it here. I've also previously submitted some theorems about finite differences, and this is somewhat related to that topic. I'd like to include these in my graduation thesis, which is why I'm trying to submit this PR. If it could be merged into the IMO problem file, that would also be great.
