备注
The value of the DiscretizationMethod element determines how values for the DimensionAttribute or ScalarMiningStructureColumn are discretized, or organized into a specific set of groups. For more information about discretization methods, see 离散化方法.
The value of this element is limited to one of the strings in the following table.
| Value | Description |
|---|---|
Automatic |
Equivalent to the AUTOMATIC discretization method for mining structure columns. |
EqualAreas |
Equivalent to the EQUAL_AREAS discretization method for mining structure columns. |
Clusters |
Equivalent to the CLUSTERS discretization method for mining structure columns. |
Thresholds |
Equivalent to the THRESHOLDS discretization method for mining structure columns. |
EqualRanges |
Equivalent to the EQUAL_RANGES discretization method for mining structure columns. |
The enumeration corresponding to the allowed values for DiscretizationMethod in the Analysis Management Objects (AMO) object model is DiscretizationMethod.
