Merci beaucoup Damien pour cette excellente vidéo.

Je retiens particulièrement l'astuce, lorsque l'on a un petit jeu de données, de l'utilisation du PRESS R2 (Leave One-Out Cross Validation) et surtout comment la déclencher dans la plateforme Stepwise Fit.

Merci Stéphane, oui le PRESS R² est en effet bien pratique dans le cas des petits jeux de données du type DOE. De même que le PRESS RMSE qui donne une idée de l'incertitude de prédiction du modèle (prendre 2*PRESS RMSE).

Attention toutefois, comme indiqué lors de l'exposé, le PRESS R² n'est pas complètement insensible au risque de sur-ajustement.
