Constructor give the antecedent, the consequent, the support and the confidence.

|
Returns the antecedent of the association rule. Cannot return null.
Implements kddml.Core.DataMining.AssociationRules.AssociationRuleManager. |
|
Returns the consequent of the association rule. Cannot return null.
Implements kddml.Core.DataMining.AssociationRules.AssociationRuleManager. |
|
Returns the support of this rule in the model as a percentage of the total number of transactions. It is a number between 0 and 1, inclusive.
Implements kddml.Core.DataMining.AssociationRules.AssociationRuleManager. |
|
Returns the support for this rule in terms of absolute count of transactions supporting it.
Implements kddml.Core.DataMining.AssociationRules.AssociationRuleManager. |
|
Returns the confidence of this rule in the model as a percentage of the total number of transactions. It is a number between 0 and 1, inclusive.
Implements kddml.Core.DataMining.AssociationRules.AssociationRuleManager. |
|
Returns the size of this rule in terms of the number of items in antecedent and consequent. Returns a value >= 2.
Implements kddml.Core.DataMining.AssociationRules.AssociationRuleManager. |
|
Tests if this rule satisfy an input transaction. A transaction satisfy a rule I1, ..., In --> In+1, ..., Im if every item Ii with i in [1, m] occurs in the transaction.
Implements kddml.Core.DataMining.AssociationRules.AssociationRuleManager. |
|
Returns a representation of this object as string.
|
|
Tests if two rules are equal.
Implements kddml.Core.DataMining.AssociationRules.AssociationRuleManager. |
|
Test if an association rule contains an input itemset. Return true if the association rule contains the itemset in the body or in the head.
