ROC.pm - A Perl module implementing receiver-operator-characteristic (ROC)
          curves with nonparametric confidence bounds

    Copyright (c) 1998 Hans A. Kestler. All rights reserved.
    This program is free software; you may redistribute it and/or

 This code implements a method for constructing nonparametric confidence
 for ROC curves described in
       R.A. Hilgers, Distribution-Free Confidence Bounds for ROC Curves,
       Meth Inform Med 1991; 30:96-101
 Additionally some auxilliary functions were ported (and corrected) from
 Fortran (Applied Statistics, ACM).


 A graphical userinterface for drawing and printing these ROC curves is
 supplied with the module (roc_ui.pl).
