Association Model Options
The algorithm for Association models is the Apriori algorithm. The defaults have been selected to work well in most cases. You can change the following:
- Minimum Support: A number between 0 and 100 indicating a percent. Smaller numbers result in slower builds and require more system resources. The default is 5%.
- Minimum Confidence: Confidence in the rules; a number between 0 and 100 indicating a percent. Smaller numbers result in slower builds and require more system resources. The default is 10%.
- Limit Number of Attributes in Each Rule: The default is to check this option. The maximum number of attributes in each rule; this number must be an integer between 2 and 20. Higher numbers of rules result in slower builds. The default value is 3. You can change the number of attributes in a rule, or you can specify no limit for the number of attributes in a rule. To specify no limit, click the checkbox to uncheck it. Specifying a large number of attributes in each rule increases the number of rules considerably.
For more information about the algorithm, including these options, see Apriori Algorithm.
