Normalized Equal Distance

Context

• Normalized Equal Distance is one of the Automatic Discretization algorithms for Continuous variables in Step 4 — Discretization and Aggregation of the Data Import Wizard.

Algorithm Details & Recommendations

• The Normalized Equal Distance algorithm pre-processes the data with a smoothing algorithm to remove outliers before computing equal partitions.
• As a result, the algorithm is less sensitive to outliers than the Equal Distance algorithm.
• The algorithm also takes into account the Minimum Interval Weight that defines the minimum prior probability of a bin.
• You can adjust the default Minimum Interval Weight under Main > Menu > Window > Preferences > Discretization.
