[en] This note first reviews methods used for checking the assumptions in linear regression (lack of fit, normality, homoscedasticity and independance of the residuals) and then describes variables transformations as remedial action when the assumptions are not fulfilled. [fr] Cette note décrit d'abord les méthodes permettant de vérifier les conditions d'application de la régression (adéquation du modèle, normalité, homoscédasticité et indépendance des résidus) et présente ensuite les transformations de variables pouvant être utilisées en cas de non-respect de ces conditions d'application.
