Interlaboratory comparisons of chemical measurements: Quo Vadis?
Bibliographic record
Abstract
Abstract In numerous articles and editorials, many of which were published in ACQUAL, Paul De Bièvre laid out challenges time and again about how the application of statistical methods can help improve our understanding of chemical measurements. Paul’s insights and incisive criticism were as illuminating and as provocative as in all other areas that he looked into—from counting to consensus building, from the validity of common statistical assumptions to the impact of model uncertainty. This memorial contribution briefly revisits some of these concerns illustrated by examples from interlaboratory comparisons and proposes an optimistic outlook for how the statistical arts practised in close collaboration between chemist and statistician will continue to add value to the chemical sciences.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
