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.
