Defining minimum support

For a general description refer to Support in an association rule.

To define the minimum support that a rule must exceed to be calculated, use the DM_setMinSupport method to set the minimum support in the DM_RuleSettings value such as:
 IDMMX.DM_RuleSettings()..DM_setMinSupport(25)
If you do not set the minimum support, the algorithm estimates a useful level for it.
Note: DM_setMinSupport takes a percentage value as its input parameter, that is, for example, 25 rather than 0.25.

To retrieve the value set for minimum support, use the method DM_getMinSupport.
