arules

Description

The arules command looks for associative relationships between field values. The command returns a table with the following columns: Given fields, Implied fields, Strength, Given fields support, and Implied fields support. The given and implied field values are the values of the fields you supply. The Strength value indicates the relationship between (among) the given and implied field values.

Implements arules agorithm as discussed in Michael Hahsler, Bettina Gruen and Kurt Hornik (2012). arules: Mining Association Rules and Frequent Itemsets. R package version 1.0-12. This algorithm is similar to the algorithms used for online shopping websites which suggest related items based on what items other customers have viewed or purchased.
