hello everyone,I tried to write a code for roc curve using perl module statistic:roc, but when i run the program it gives the error value out of range for table lookup (2):0.711752437,1 at line 16.

 use Statistics::ROC;
 open(fh,"<roc_tp_fp.txt");
 while ( <fh> ) {
 ($a,$b)=split/,/;
    push @AoA, [ split ];
 }
 for $aref ( @AoA ) {
    #print "[ @$aref ],";
 }
@curves=roc('decrease',0.95,@AoA);
   print "$curves[0][2][0]  $curves[0][2][1] \n";

input_file:roc_tp_fp.txt looks like as follows: 0.9883817,1 0.770431568,1 0.983195895,1 0.812109932,1 0.901505931,1 0.72431528,1 0.73553418,1 0.724572657,1
