title: Remove Weka Instances if one or more attributes have certain value
body: <p>I have a dataset with multiple numeric attributes and a nominal class, like</p>
  
  <pre><code>@relation Example
  
  @attr_1 numeric
  @attr_2 numeric
   ...
  @attr_n numeric
  @class {yes, no}
  
  @data
  2,4,...,10,yes
  -1,-1,...,3,yes
  2,3,...,-1,no
  12,6,...,4,no
  </code></pre>
  
  <p>Usually values are bigger than zero, but it appears that one or more numeric attributes can have a negative value <code>-1</code>.</p>
  
  <p><strong>How can I remove the instances with at least one attribute having a negative value?</strong></p>
  
  <p>I already found <a href="https://stackoverflow.com/questions/19136310">this</a> but I don't explicitly know in which attribute the negative value appears. So, does someone know another more fitting Filter to this problem?</p>
