<A NAME="shouldCalculateWeights()"><!-- --></A><H3>
shouldCalculateWeights</H3>
<PRE>
public boolean <B>shouldCalculateWeights</B>()</PRE>
<DL>
<DD>Returns true if the user wants to calculate feature weights (depending on
 a parameter). In this case the method getWeights() must also be overriden
 and deliver the calculated weights. The default implementation returns
 false.
