Specific residue: application of orthogonal contrasts when heteroscedasticity is present Resíduo específico: aplicação de contrastes ortogonais na presença da heterocedasticidade
When experimental data are submitted to analysis of variance, the assumption of data homoscedasticity (variance homogeneity among treatments), associated to the adopted mathematical model must be satisfied. This verification is necessary to ensure the correct test for the analysis. In some cases, wh...
