Reference commit e577c1669e
This script lives in the mathlib-ci repository. To run it locally, from your mathlib4 directory:
git clone https://github.com/leanprover-community/mathlib-ci.git ../mathlib-ci
../mathlib-ci/scripts/reporting/technical-debt-metrics.sh pr_summary
- 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).
Also fix the variable implicitness and and names of a few existing declarations. Renames: * `coe_finsetSum` to `ofNNReal_finsetSum` * `coe_finsetProd` to `ofNNReal_finsetProd`
