SCREAM (Shifted Covariates REgression Analysis for Multi-way data) combines PARAFAC2 and principal covariates regression (PCovR) for multi-way regression. Overcomes inaccuracy from shifts or peak shape changes in one mode common in hyphenated chromatography. Combines PARAFAC2 decomposition with PCovR-like regression coefficients, performing as well or better than N-PLS on real and simulated datasets.
