<DL>
<DD>Parses a given list of options. Valid options are:<p>

 -C num <br>
 The class for which threshold is determined. Valid values are:
 1, 2 (for first and second classes, respectively), 3 (for whichever
 class is least frequent), 4 (for whichever class value is most 
 frequent), and 5 (for the first class named any of "yes","pos(itive)",
 "1", or method 3 if no matches). (default 3). <p>

 -W classname <br>
 Specify the full class name of classifier to perform cross-validation
 selection on.<p>

 -X num <br> 
 Number of folds used for cross validation. If just a
 hold-out set is used, this determines the size of the hold-out set
 (default 3).<p>

 -R integer <br>
 Sets whether confidence range correction is applied. This can be used
 to ensure the confidences range from 0 to 1. Use 0 for no range correction,
 1 for correction based on the min/max values seen during threshold 
 selection (default 0).<p>

 -S seed <br>
 Random number seed (default 1).<p>

 -E integer <br>
 Sets the evaluation mode. Use 0 for evaluation using cross-validation,
 1 for evaluation using hold-out set, and 2 for evaluation on the
 training data (default 1).<p>

 Options after -- are passed to the designated sub-classifier. <p>
