Description

Induce a set of strong sequence rules from a set of frequent sequences, i.e. which (1) satisfy the minimum confidence threshold and (2) which contain the last element of the generating sequence as the right-hand side (consequent) sequence.

Usage

## S3 method for class 'sequences':
ruleInduction(x, transactions, confidence = 0.8, control = NULL)

Arguments

x

an object.

transactions

currently not used.

confidence

a numeric value specifying the minimum confidence threshold.

control

a list with logical components maximal specifying if rules should be induced from maximally frequent sequences only, and verbose if progress and runtime information should be displayed.

Value

• Returns an object of class sequencerules.
