Remarks
This enumeration describes the type of content represented by a mining structure column, and can be extended as needed by mining algorithm providers. For more information about content types, see Content Types (Data Mining).
The values listed in the following table are typically supported by all mining algorithm providers.
Value |
Description |
|---|---|
Discrete |
The column contains discrete values. |
Continuous |
The values for the column define a continuous set of numeric data. |
Discretized |
The values in the column represent groups (or buckets) of values derived from a continuous column. |
Ordered |
The values for the column define an ordered set. |
Cyclical |
The values for the column define a cyclical ordered set. |
Probability |
The values for the column specify a probability for the columns contained in the ClassifiedColumns element of the parent ScalarMiningStructureColumn. |
Variance |
The values for the column specify a variance for the columns contained in the ClassifiedColumns element of the parent ScalarMiningStructureColumn. |
StdDev |
The values for the column specify a standard deviation for the columns contained in the ClassifiedColumns element of the parent ScalarMiningStructureColumn. |
ProbabilityVariance |
The values for the column specify a probability variance for the columns contained in the ClassifiedColumns element of the parent ScalarMiningStructureColumn. |
ProbabilityStdDev |
The values for the column specify a probability standard deviation for the columns contained in the ClassifiedColumns element of the parent ScalarMiningStructureColumn. |
Support |
The values for the column specify support information for the column contained in the ClassifiedColumns element of the parent ScalarMiningStructureColumn. Note This column is provided as part of the standard for third party mining algorithm providers. Note Microsoft provided algorithms do not have any use for this column. . |
Key |
The column is a key column. Note This content type is applicable only to key columns, in which the IsKey element is set to True. |
In addition to these standard values, mining algorithm providers included with Microsoft SQL Server Analysis Services support the values in the following table.
Value |
Description |
|---|---|
Key Sequence |
The column is a key column, and the values for the column represent a sequence of events. Note This content type is applicable only to key columns, in which the IsKey element is set to True. |
Key Time |
The column is a key column, and the values for the column represent time measurement units. Note This content type is applicable only to key columns, in which the IsKey element is set to True. |
Sequence |
The values for the column represent a sequence of events. |
Time |
The values for the column represent time measurement units. |
The enumeration corresponding to the allowed values for Content in the Analysis Management Objects (AMO) object model is ScalarMiningStructureColumn.
