en Cochran-Mantel-Haenzel test for repeated tests of independence is a statitiscal test which allows the comparison of two groups on a dichotomous/categorical response. It is used when the effect of the explanatory variable on the response variable is influenced by covariates that can be controlled. It is often used in observational studies where random assignment of subjects to different treatments cannot be controlled, but influencing covariates can.
The null hypothesis is that the two nominal variables that are tested within each repetition are independent of each other. So there are 3 variables to consider: two categorical variables to be tested for independence of each other, and the third variable identifies the repeats.
fr Publié en 1959 par Nathan Mantel, William Haenszel et basé sur les travaux de William Gemmel Cochran de 1954, le test du \chi^2 de Cochran-Mantel-Haenszel est une approche non paramétrique permettant de tester si « l’odds ration commun » associé à une succession de tableaux croisés dynamiques issue de variables qualitatives deux à deux appariées (X ^{t_1}, X ^{t_2}), (X ^{t_2}, X ^{t_3}), (X ^{t_3}, X ^{t_4}), \cdots , (X ^{t_{n - 2}}, X ^{t_{n - 1}}), (X ^{t_{n - 1}}, X ^{t_n}) à 2 modalités s’éloigne de 1 ou non. On rappel qu’une odds ratio égal à 1 implique une pente inexistante
