Remarks
This enumeration describes the type of content represented by a mining structure column, and can be extended as needed by mining algorithm providers.
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. Microsoft provided algorithms do not make use of 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 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.
