Abstract: | This paper studies the two-factors design model when the heteroscedasticity of variance is present in errors. As can be observed, testing of hypothesis based on the main effects for this design model can be performed using Hotelling's T2 test. Simultaneous confidence intervals are also proposed. Finally, the proposed methodology is applied to a real-life example En el presente trabajo se estudia el modelo de diseño de dos factores cuando se presenta la heteroscedasticidad de varianza en los errores. Como se verá, la prueba de hipótesis sobre los efectos principales para tal modelo de diseño se puede realizar a través del estadístico T2 de Hotelling. Además son propuestos intervalos de confianza simultáneos. Finalmente la metodología propuesta es aplicada a un ejemplo real |
