Rééchantillonnage, randomisation et dominance : mieux cerner ces entités exotiques du bestiaire statistique
Bibliographic record
Abstract
Ces dernières décennies ont vu l’émergence des tests par rééchantillonnage, de randomisation ou de dominance stochastique. Ce court article vise à démystifier les principes sous-jacents à ces procédures statistiques parfois considérées exotiques, mais de plus en plus utilisées en recherche. L’article présente un exemple appliqué au test de dominance par randomisation avec le logiciel libre de droits jamovi. À la suite de la lecture de cet article, vous serez en mesure de cerner les atouts des tests de randomisation comparativement aux tests paramétriques et non-paramétriques classiques, et saurez comment interpréter un exemple introductif à ce sujet.

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.
