title: What are the column definitions for H2O's gains/lift table?
body: <p>H2O's <a href="http://docs.h2o.ai/h2o/latest-stable/h2o-docs/flow.html#interpreting-the-gains-lift-chart" rel="nofollow noreferrer">documentation</a> doesn't provide clear definitions for each column in the gains/lift table output. I'm not sure how the capture rate is being calculated, and there is a <em>score</em> column that is not mentioned in the documentation.</p>
  
  <p><a href="https://i.stack.imgur.com/6FSFf.png" rel="nofollow noreferrer">Here's what the output looks like.</a></p>
  
  <p>The raw java file is <a href="https://github.com/h2oai/h2o-3/blob/master/h2o-core/src/main/java/hex/GainsLift.java" rel="nofollow noreferrer">here</a> -- I tried finding the answer to my question in there but had difficulty making sense of it. Thanks.</p>
