|Publication Date:||1 July 2018|
|ICS Code (Application of statistical methods):||03.120.30|
This practice provides a step by step procedure for the application of the Generalized Extreme Studentized Deviate (GESD) Many-Outlier Procedure to simultaneously identify multiple outliers in a data set. (See Bibliography.)
This practice is applicable to a data set comprising observations that is represented on a continuous numerical scale.
This practice is applicable to a data set comprising a minimum of six observations.
This practice is applicable to a data set where the normal (Gaussian) model is reasonably adequate for the distributional representation of the observations in the data set.
The probability of false identification of outliers associated with the decision criteria set by this practice is 0.01.
It is recommended that the execution of this practice be conducted under the guidance of personnel familiar with the statistical principles and assumptions associated with the GESD technique.
