Example of Association Rules {Diaper} → {Beer}, {Milk, Bread} → {Eggs,Coke}, {Beer, Bread} → {Milk}, Implication means co-occurrence, not causality
chap basic association analysis
Itemsets associated with the aforementioned rules are: {Bread, Butter}, and {Butter, Eggs} The support of each individual itemset is at least 40 (see Table 2) Therefore, all of these itemsets are large The confidence of each rule is presented in Table 3
