Abstract

fetched live from OpenAlex

L'analyse de classes latentes (ACL) permet de partager et de distinguer des sous-groupes non observables (latents) d'individus sur la base de leurs r ˊeponses ˋa un ensemble d'indicateurs observables (manifestes).Cette analyse permet de mieux comprendre la variabilit ˊe au sein d'une population.Or, il existe peu de documentation, surtout en français, sur la proc ˊedure ˋa suivre pour r ˊealiser une ACL sur la plateforme R. Ce logiciel statistique est accessible gratuitement et comporte de nombreux avantages en ce qui a trait ˋa la programmation d'analyses, ˋa la visualisation des donn ˊees ainsi qu' ˋa la gestion des variables et de l'environnement de travail.L'objectif du pr ˊesent article est d'exemplifier la r ˊealisation d'une ACL sur la plateforme R avec le package poLCA.Apr ˋes une introduction sur l'origine et les principes de l'ACL, un tutoriel sur la r ˊealisation d'une ACL avec R est pr ˊesent ˊe.Une situation hypoth ˊetique portant sur la perp ˊetration de violence dans les relations amoureuses ˋa l'adolescence est utilis ˊee.La syntaxe R permettant de r ˊealiser cette analyse est fournie et explicit ˊee en d ˊetails.Dans une vis ˊee de partage des connaissances, similaire ˋa la philosophie de R, cet article peut servir de guide pour tout ˊetudiant ou chercheur voulant d ˊevelopper sa compr ˊehension de l'ACL et ses comp ˊetences en statistiques sur cette plateforme.

Not 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.
