摘要：

Objective: To compare the performance of Grubbs outlier detection procedure with recursive Extreme Studentized Deviate (ESD) outlier detection procedure. Design and methods: Using simulated data, the powers of Grubbs' and ESD procedures were evaluated. Results: Except when the sample contained exactly one outlier, the power of ESD procedure was higher than that of Grubbs' procedure. Conclusion: The ESD recursive procedure is the procedure of choice to detect multiple Outliers in environmental and chemical data. (C) 2010 The Canadian Society of Clinical Chemists.
