 Specify the percentage rate at which attributes are eliminated per invocation
 of the support vector machine. This setting trumps the constant rate setting. 
 Default = 0 (percentage rate ignored).<p>

 Specify the threshold below which the percentage elimination method
 reverts to the constant elimination method.<p>
