Version 2007.6 of XLSTAT is available and brings the following new features:
- Canonical correlation analysis has been added to the ADA module.
- The GPA function, available in both the MX and ADA is now more flexible as you can now easily select configurations that do not have the same number of dimensions. This is very useful in sensory data analysis.
- The GPA algorithm has been upgraded. It is significantly quicker and offers a new alternative approach for missing data : if a missing data is met for a given triplet object/configuration/dimension, the data are considered as missing for the couple object/configuration. Then, it is not necessary to consider the couple configuration/dimension or the whole object as being missing. This option has advantages that should be discribed soon in an article.
- The PLSPM module has been improved.

The XLSTAT User Conference took place in Paris (France) at the “Maison de la Recherche” during the 7th and 8th June 2007. With a much larger number of attendees than initially planed, this conference was big success with an essentially European audience.

The presentations of internationally known experts like Michael Greenacre or Michel Tenenhaus allowed the users to enrich their knowledge of essential methods like Correspondence Analysis or PLS regression. Vincenzo Esposito Vinzi presented the PLS path modeling, that is now available in the module PLSPM of XLSTAT.

Finally the conference allowed the users to imagine new perspectives for using XLSTAT, especially with the version 2007 of Excel and with the possibility of using VBA to programmatically control XLSTAT.
