title: How does WEKA treat nominal attributes v/s numerical attributes?
body: <p>If one of my columns in the data set has just 3 possible values .i.e. 0, 1 and 2, how differently does WEKA treat them if I declare them as nominal v/s numerical?</p>
  
  <p>Also, if I have a large number of nominal values for an attribute for a column, is there an easy way to declare this nominal attribute which has a very high ordinal value?</p>
