Hi Karen,

The ASSOC procedure runs behind the scenes of the Association node in SAS Enterprise Miner.

The goal is to find rules for items that appear together in a transaction data set, as well as calculating the support and confidence for such rules.

Here a screenshot of the results of Association node items link graph and support vs confidence plots.

The easiest is to use the Association node in SAS Enterprise Miner. However, if you want to understand the technical side of Association node, take a look at this document. It describes how how PROC DMDB, PROC ASSOC, and PROC RULEGEN work together.

I hope this helps!
