Line 1: Line 1:
* The October 2007 and the November 2007 versions do not evaluate DATA_RANGE= in the CORRECT step. The August 2007 version, and versions since December 2007 do.
* The June and July 2008 versions suffer from a bug in the CORRECT step: the correlation coefficient against a reference data set is always 0.00, and therefore sometimes the wrong decision is made concerning re-indexing of the data. Example taken from CORRECT.LP produced with xds_par:
CORRELATION  NPAIR  Rmeas  COMPARED  ESD      REINDEX TRANSFORMATION
      0.00211818312  25.1  53803    1.65  1  0  0  0  0  1  0  0  0  0  1  0
  *  0.00260052808  25.1  53803    1.65  1  1  0  0 -1  0  0  0  0  0  1  0
whereas xds produces the correct output:
CORRELATION  NPAIR  Rmeas  COMPARED  ESD      REINDEX TRANSFORMATION
  *  0.89    5960  25.1  53803    1.65  1  0  0  0  0  1  0  0  0  0  1  0
      0.06    5960  25.1  53803    1.65  1  1  0  0 -1  0  0  0  0  0  1  0
For me, xds_par produced the problem, but not xds.


This is fixed in XDS versions starting September 2008.
