Ajoutez un test de Breusch-Pagan (statsmodels.stats.diagnostic.het_breuschpagan) pour quantifier l'hétéroscédasticité et un test de Shapiro-Wilk (scipy.stats.shapiro) sur les résidus pour vérifier leur normalité au-delà du Q-Q plot. Cela transforme l'analyse visuelle en diagnostic statistique robuste.
