Résumé
"This paper studies the two-factors design model when the heteroscedasticity of variance ispresent in errors. As can be observed, testing of hypothesis based on the main effects for thisdesign model can be performed using Hotelling's T 2 test. Simultaneous confidence intervalsare also proposed. Finally, the proposed methodology is applied to a real-life example."
