title: Arules in R: A very high measure for lift
body: <p>Running Apriori with the Arules package, generates rules with very high lift. </p>
  
  <p>For example:</p>
  
  <p><code>A -&gt; B support=0.0023 confidence=0.6832 lift=28.02</code></p>
  
  <p>(min_support=0.002 and min_conf=0.2)</p>
  
  <p>In some rules, the lift is as high as 250! I have seen people discuss a lift greater than 1 (most of them &lt;5), but I'm wondering how I can interpret these rules with very high lift values. </p>
