• 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).

Thanks!

[grunweg]

I'm slightly surprised this one is useful, but I'll trust you (and could have verified with later PRs).

[grunweg]

Never mind: FredholmPackage.eventually_isInvertible uses this (and there it seems useful).

[ADedecker]

To be fair this is pure convenience, but I believe this is an instance of Mathlib preferring convenience over a more minimal API.
