title: How do I compare two classifiers in Weka using the Paired T-test
body: <p>In Weka I can go to the experimenter.  In the set-up I can load in an .arff file, and get weka to create a classifier (i.e. J48), then I can run it and then finally I can go to the analyze tab.  In this tab it gives me an option to 'testing with Paired T-Test' but I cannot figure out how to create a second classifier (i.e. J48 unpruned) and do a T-Test on the two results.</p>
  
  <p>Google does not lead me to any tutorial or answers.  </p>
  
  <p>How can I get Weka to do a T-Test on the results of two different classifiers, made from the same data?</p>
