XLSTAT-PLSPM

XLSTAT-PLSPM is the only software that allows using the PLS approach (PLS Path modeling) without leaving Microsoft Excel. The first presentation of the finalized PLS approach to path models with latent variables was published by Herman Wold in 1979, with further works on the algorithm published in 1982 and 1985. Then, Wold's work was continued by J.-B. Lohmöller (1989) who formalized the method from the mathematical point of view before developing the LVPLS software where the PLS algorithm was enriched by a few validation procedures. After Lohmöller's contribution, the method was somehow forgotten, and it is only since a decade that it has been rediscovered by Wynne W. Chin in the domain of Information Systems and then by Michel Tenenhaus and Vincenzo Esposito Vinzi in the domain of Statistics, and further developed thanks to the efforts of several researchers from diverse disciplines at both the methodological and the application level.

The PLS approach is a powerful data exploration tool, as soon a you are in a case where you can define concepts that cannot be directly measured (the latent variables) and are interconnected (one can draw a causal graph), but that can be related to measured variables (the manifest variables). This method is in many cases an alternative to the SEM methods (Structural Equation Modeling), and a powerful substitute in the cases where SEM cannot be used.

XLSTAT-PLSPM implements all methodological features and most recent findings of the PLEASURE (Partial LEAst Squares strUctural Relationship Estimation) technology. This technology has been originally developed as a research tool at the academic level by Y.M. Chatelin and V. Esposito Vinzi in co-operation with C. Lauro and M. Tenenhaus. The partnership Addinsoft has established with them allows to keep XLSTAT-PLSPM at the top of the edge, while making the solution available to anyone.

Thanks to an intuitive and flexible interface, XLSTAT-PLSPM allows to build the graphical representation of the model, then to fit the model, display the results in Excel either as tables or graphical views. As XLSTAT-PLSPM is totally integrated with the XLSTAT suite, it is possible to further analyze the results with the other XLSTAT features.

An in-depth description of the method is available in the XLSTAT help documents. Furthermore, a tutorial demonstrates how to create a PLSPM model and to interpret the results.

Demo version

A trial version of XLSTAT-PLSPM is included in the main XLStat-Pro download.

Ordering XLStat-PLSPM

The prices, in UK£ and US$, for academic and commercial users are listed below. There are two ordering options:

1. E-mail only - a registration code will be e-mailed to you that will unlock the demo version of the program from our web site.
2. With CD-ROM - this costs an additional £15 ($30) + shipping & handling.

You can order on-line using our secure shopping cart facility below. Simply choose the required item and price and press the "Add to cart" button in that row to add the item to your shopping cart.

If you already have XLStat-Pro then use the section below to order just the advanced module. Please send us your original XLStat-Pro serial number, either in the Special Instructions section of the order form or in a separate e-mail.

Notes:

1. Academic prices (where offered) apply to students and staff at educational institutions using the software for research as well as charities/NGOs and residents of least developed countries. Governmental bodies pay the commercial price. Commercial prices also apply if the software is to be used for commercial consulting within universities.
2. VAT - Customers within the UK will have Value Added Tax at 17.5% added to the order. Those in other countries in the European Union will also have VAT added, unless they are registered for VAT in their own country and supply their registration number with their order (in the "Special Instructions" section at checkout). Our VAT registration number is GB 625 3760 41.
3. If you wish to order by fax or postal mail, or need to pay by means other than credit card, then you can also use the shopping cart above, but choose the appropriate option when you check out. You can also print out and use our printed order form.
4. All credit card orders are charged in British pounds. The US$ prices apply only when paying in US$ by check (drawn on a US bank) or bank transfer.
5. Your order will normally be processed within two working days. Orders outside of the United Kingdom are shipped by air-mail. Within the UK first class post is used.
6. All prices above are for single computer/user licenses. The program may only be used on a single computer, or by a single user on up to two computers (i.e. a single user can use it on both an office computer and a laptop, so long as no one else is using those computers). Contact us for discounts on multiple copies and site licenses.
