Github user andrewpalumbo commented on the issue:

    https://github.com/apache/mahout/pull/300
  
    this is not really apropos of this PR, but looking through, reminded me that we have some
a classification stats package in https://github.com/apache/mahout/tree/master/math-scala/src/main/scala/org/apache/mahout/classifier/stats.
 There may be some useful code there, that could be refactored into to the new framework.
