Prediction-weighted partial least-squares (PWPLS) is a progressive approach of partial least-squares (PLS) regression. PWPLS is a simple, efficient, and evolutionary algorithm to select appropriate predictor variables, and weight each selected predictor variable for improving predictability when the
There are two commonly used partial least squares (PLS) regression algorithms. 1 -3 The first, the orthogonal scores algorithm, is the older one, 4 whereas the second, the orthogonal loadings algorithm, is more recent. 5 Their difference lies in the decomposition of the data matrix X = β r i =1 t i
