Public Property DiscretizationMethod As DiscretizationMethod

Property Value

Type: Microsoft.AnalysisServices.DiscretizationMethod

A DiscretizationMethod object containing the method to be used for discretization.

Remarks

The value of DiscretizationMethod determines how values for the DimensionAttribute are discretized, or organized into a specific set of groups.

This property can be set to the following values:

For data mining, the method that is used to discretize data can be different depending on whether your data is relational or stored in an OLAP dimension.

For OLAP data mining, the algorithm automatically computes the number of buckets to generate, by using the following equation, where n is the number of distinct values of data in the column:

Number of Buckets = sqrt(n)

If you do not want Analysis Services to calculate the number of buckets, you can use the?DiscretizationBucketCount property to manually specify the number of buckets.

For more information about discretization methods in data mining solutions, see Discretization Methods (Data Mining).
