No, this is a bug in the program. The value 4 is written whatever
the number of components. Note that this is only a problem in the
listing. The file itself has the right number of columns.

This is possible with the ADEScatters module, which is unfortunately
only available in the Macintosh version of ADE-4. You can however
do it with the Curves module but one variable at a time (i.e., all
components for one variable, or conversely).

You may ask them directly to him :

Note that he also recently published a book on PLS regression (in French),
which should be easily available :

Tenenhaus, M. (1998). La régression PLS. Technip, Paris.
