【 摘 要 】

This paper provides a methodology alternative for the detection of influential observations in factorial design of fixed effects 3ω. Our proposal is developed through the approach of the test statistic (Fq), and the characterization of the impact of such observations on the analysis, the sums of squares and the estimators of the model that describes the experimental design.
