I believe that the original poster was asking about Partial Least
Squares (PLS) regression (see Garthwaite, P. H. (1994), "An
Interpretation of Partial Least Squares", JASA, Vol 89, No 425, pp
122-127), and that your description of "partial regression" is a
different technique, useful in other situations.
