Multivariate Curve Resolution Alternating Least Squares
(MCR-ALS)
Description
Alternating least squares is often used to resolve
components contributing to data with a bilinear structure; the
basic technique may be extended to alternating constrained
least squares. Commonly applied constraints include
unimodality, non-negativity, and normalization of components.
Several data matrices may be decomposed simultaneously by
assuming that one of the two matrices in the bilinear
decomposition is shared between datasets.
