Modeling Flags (DMX)
You can use modeling flags in Analysis Services to provide additional information to a data mining algorithm about the data that is defined in a case table. The algorithm can use this information to build a more accurate data mining model. You can define modeling flags on both mining structure columns and mining model columns.
Analysis Services supports the following modeling flags:
Third-party algorithms may support additional modeling flags. To determine which modeling flags an algorithm supports, use the SUPPORTED_MODELING_FLAGS schema rowset. You can also query the mining services on the server to determine which modeling flags are supported for a particular algorithm. For example, the following query returns the modeling flags are supported for the Microsoft Linear Regression algorithm on the current server:
SELECT SUPPORTED_MODELING_FLAGS FROM $SYSTEM.DMSCHEMA_MINING_SERVICES WHERE SERVICE_NAME = 'Microsoft_Linear_Regression'
For examples of the syntax that Analysis Services supports for specifying a flag on a mining structure column, see CREATE MINING STRUCTURE (DMX).
For an example of the syntax for specifying a modeling flga on a mining model column, see ALTER MINING STRUCTURE (DMX).
