5.1 Public Interface


5.1.1 Ordinary functions

Function: apriori (dataset &key support confidence test)

Calculates the association rules in the dataset using the apriori algorithm. Expects a dataset of the form

(2 3 8)
(2 0)),
where each line is a transaction.
Returns a list of the mined rules.
