Putting a Support Threshold in Apriori Algorithm - SAS E-miner

[NJSAS]

Hi,

I need guidance on setting a threshold for the "support" in Apriori Algorithm using SAS E-miner. The package has a threshold for confidence but not support.

Kindly advise.

Thanks.

I need guidance on setting a threshold for the "support" in Apriori Algorithm using SAS E-miner. 

The Association node in SAS Enterprise Miner allows you to specify the Minimum Confidence level and the minimum support either measured by count or percentage using the following node properties: 

   *  Minimum Confidence Level - specifies the minimum confidence level that is required to generate a rule.

   *  Support Type - specify minimum support based on Count or Percent, and then set the appropriate parameter below: 

         -- Support Count - specifies the minimum transaction frequency to support an association. 

         -- Support Percentage - specifies the minimum transaction frequency to support an association.

I hope this helps!

Doug
