Compte rendu du colloque "Mthodes Quantitatives en Sciences Humaines (MQSH) 2023"

The 12th annual meeting Quantitative Methods in the Humani-ties (Methodes quantitatives en sciences humaines, MQSH) was held on June 9, 2023 at Universite TeLUQ, Montreal. Seven speakers presented their research findings. Sebastien Beland assessed the effectiveness of various popular coefficients on unidimensional items with dichotomous responses. Felix Laliberte presented StepMix, a Python and R package for model-based clustering and mixture (latent classes, latent profiles). Eric Frenette presented the methodological and statistical challenges encountered during the evaluation of the longitudinal program Gagnant pour la vie (version 1.0 ; Eng. Win for life) implemented in a sports-oriented school in Quebec. Andre Achim presented a new technique for symmetrizing asymmetrical distributions. Pier-Olivier Caron presented a comparison of the statistical properties of longitudinal and cross-sectional mediation models. Denis Cousineau presented two techniques analogous to ANOVA: analysis of proportions using the arcsine transfor-mation (ANOPA) and analysis of data frequencies (ANOFA). Louis Laurencelle proposed a complete and parametrically plausible test of the difference between two paired proportions.
