A data macro is also known as a(n):

A) IF macro. B) conditional macro. C) comparison macro. D) event-driven macro.

A characteristic rule is a rule of the form {p} ?? {q1, q2,...,qn}, where the rule antecedent contains only a single item. An itemset of size k can produce up to k characteristic rules. Let ? be the minimum confidence of all characteristic rules generated from a given itemset: Is ? monotone, anti-monotone, or non-monotone?

For each of the following measures, determine whether it is monotone, anti-

monotone, or non-monotone (i.e., neither monotone nor anti-monotone).
