Excel Basics to Blackbelt by Dr. Elliot Bendoly, Associate Professor at the Goizueta Business School, Emory University, is recommended by Addinsoft, as it is designed to enhance the skills of Excel users, to enable them to reach to a level of mastery that will allow them to develop user interfaces and automated applications. To accomplish this, the major theme of the text is “the integration of the basic”; as a result readers will be able to develop decision support tools that are at once highly intuitive from a working-components perspective but also highly significant from the perspective of practical use and distribution. Applications integration discussed includes the use of MS MapPoint, XLSTAT and RISKOptimizer, as well as how to leverage Excel’s iteration mode, web queries, visual basic code, and interface development. There are ample examples throughout the text.

If you place you order before June 30 2008, you will can benefit from a 20% discount. Order form can be download by clicking here : Excel Basics to Blackbelt.

April 28, 2008

Addinsoft continues its efforts to constantly innovate by offering news tools oriented towards applications.

After releasing the EasyPoints tool in March, useful to any Excel user, we bring a new and unique feature in XLSTAT-ADA: PLS-CCA. PLS-CCA is a new way to do canonical correspondence analysis (CCA) with an automatic variable selection based on PLS regression. Although CCA is mostly used by ecologists, we do think CCA should also be used in geo-marketing or in sensory analysis as it allows to relate measured dimensions to a contingency table.

Survival analysts will be pleased to see the Cox regression added to the XLSTAT-Life module. XLSTAT-Life users with an active maintenance plan have a free access to that upgrade.

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.
