Summary

Usage:	Market basket analysis, customer relationship management.
Input:	Transactional data consisting of items whose co-occurrence within a transaction is of interest.
Output:	Association rules identifying relationships between items within each transaction.
Complexity:	Adversely affected as the support threshold decreases, particularly for large datasets. Exponential.
Availability:	Freely available as part of the Borgelt Suite (See Chapter 25) with a Gnome-based front-end available as part the Gnome Data Mining Toolkit (See Chapter ), and integrated within R as part of the arules package (See Chapter 26). Most commercial data mining toolkits include an implementation of apriori. Examples include SPSS (See Chapter 30), SAS Enterprise Miner (See Chapter 31), and Statistica (See Chapter 36).
