Methods

Description

getItemsets(int itemsetSize): Collection

Constructs and returns a collection of the itemsets of the

specified size that allows sequential inspection of the gener-

ated itemsets of the given size.

getMaxAbsoluteSupport(): int

Returns the maximum support value of the rules contained

in the model.

getMinAbsoluteSupport(): int

Returns the minimum support value of the rules contained

in the model.

getMaxConfidence(): Double

Returns the maximum confidence value of the rules con-

tained in the model.

getMaxRuleLength(): int

Returns the largest rule length in terms of the number of

items.

getMaxTransactionSize(): int

Returns the number of items in the largest transaction in

the build data used when building the model.

getMinConfidence(): Double

Returns the minimum confidence value of the rules con-

tained in the model.

getNumberOfItems(): int

Returns the number of distinct items in the build data used

when building the model.

getNumberOfItemsets(): int

Returns the number of itemsets whose support values are

equal to or exceed the support threshold specified in the

AssociationRulesSettings used when building the model.

getNumberOfTransactions(): long

Returns the number of transactions used to build the model.

getRules(): Collection

Constructs and returns a collection of all rules in the model

that allows sequential inspection of the generated rules.

getRules(RulesFilter filter): Collection

Constructs and returns a collection of model rules as filtered

by the specified filter.

association.AssociationRule

Methods

Description

getAbsoluteSupport(): int

Returns the support for the given association rule in terms

of absolute count of transactions supporting this rule.

getAntecedent(): Itemset

Returns the antecedent of the association rule.

getConsequent (): Itemset

Returns the consequent of the association rule.

getSupport (): double

Returns the support for the given association as a percent-

age of the total number of transactions. The percentage is a

number between 0 and 100, denoted as (0,100] where 100 is

included.
