Re‐interpretation of NIPALS results solves PLSR inconsistency problem [PDF]
Journal of Chemometrics, 2008 AbstractThe well‐known nonlinear iterative partial least squares (NIPALS) algorithm is commonly used for computation of components in partial least squares regression (PLSR) with orthogonalized score vectors. Based on generalized inverse formalism, Pell et al.[1] have recently claimed that the NIPALS results are inconsistent with respect to model ...

Quantitative Assessment of Cold Injury in Tea Plants by Terahertz Spectroscopy Method
Agronomy, 2023 Cold injury (CI) causes irreversible damage to tea plants, which results in decline in the quality of famous teas and huge economic loss. A new, quick, non-destructive method is provided to assess the CI of tea leaf based on terahertz (THz) spectroscopy.

Reduced PCR/PLSR models by subspace projections [PDF]
Chemometrics and Intelligent Laboratory Systems, 2006 Abstract Latent variables models used in principal component regression (PCR) or partial least squares regression (PLSR) often use a high number of components, and this makes interpretation of score and loading plots difficult. These plots are essential parts of multivariate modeling, and there is therefore a need for a reduction of the number of ...
