Abstract
La régression logistique se définit comme étant une technique permettant dajuster une surface de régression à des données lorsque la variable dépendante est dichotomique. Cette technique est utilisée pour des études ayant pour but de vérifier si des variables indépendantes peuvent prédire une variable dépendante dichotomique. Contrairement à la régression multiple et lanalyse discriminante, cette technique nexige pas une distribution normale des prédicteurs ni lhomogénéité des variances. Différents types de régression logistique existent, possédant chacun leur procédé statistique et conduisant à lélaboration de différents modèles théoriques. Ainsi, seront abordés les types direct, séquentiel et automatisé («stepwise»). Un exemple dutilisation de cette technique avec le logiciel SPSS sera présenté et la procédure danalyse des résultats y sera détaillée, notamment en ce qui a trait à linterprétation des rapports de cote.

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.
