Outlier Treatment Transformation Welcome Page

An outlier is a data point that is located far from the rest of the data. An outlier is typically several standard deviations from the mean. Some data mining algorithms are sensitive to outliers in data; for more information, see Outliers in Oracle Data Mining.

The Outlier Treatment wizard identifies outliers and lets you specify how to handle them. You specify a strategy by defining what constitutes an outlier (for example, all values in the top and bottom 5% of all values) and you specify how to replace outliers (either with nulls or edge values). The wizard can generate default strategies based on the algorithm that you are planning to use.

After you click Finish, the view is created and its details are displayed.

This transformation processes single-record case and multi-record case data.
