title: Minimum confidence and minimum support for Apriori
body: <p>What are appropriate values for minimum confidence and minimum support values for the <a href="http://en.wikipedia.org/wiki/Apriori_algorithm" rel="nofollow noreferrer">Apriori algorithm</a>? How could you tweak them? Are they fixed values, or do they change during the running of the algorithm? If you have used this algorithm before, what values did you use?</p>
