Regression coefficients in multilinear PLS
Sijmen de Jong · Journal of Chemometrics · 1998
Three alternative approaches are discussed for finding the final calibration 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 PLS is inconsequential, it also follows that Bro's tri-PLS is equivalent to Ståhle's linear three-way decomposition (LTD). © 1998 John Wiley & Sons, Ltd.
