A version of PLS regression is described that intends to combine the c
omputer hardware implementation advantages of the algebraic technique
of 'QR decomposition' with the statistical, interpretative and computa
tional advantages of PLS regression. With a QR decomposition based on
Givens rotations, the QR-PLS technique appears to be suited for hardwa
re parallelization without sacrificing the modelling flexibility of PL
