Three alternative approaches are discussed for finding the final calib
ration model (regression coefficients) in PLS regression of k-way Y on
N-way X. The simplest approach is to skip the deflation of the X-data
. From the observation that the specific deflation used in multiway PL
S is inconsequential, it also follows that Bro's tri-PLS is equivalent
to Stahle's linear three-way decomposition (LTD). (C) 1998 John Wiley
