Cage of covariance in calibration modeling: Regressing multiple and strongly correlated response variables onto a low rank subspace of explanatory variables
Eskildsen, Carl Emil Aae; Næs, Tormod; Skou, P.B.; Solberg, Lars Erik; Dankel, Elin Katinka; Basmoen, Silje A.; Wold, Jens Petter; Horn, Siri S.; Hillestad, B.; Poulsen, Nina A.; Christensen, Mette; Pieper, Theo; Afseth, Nils Kristian; Engelsen, Søren B. (Peer reviewed; Journal article, 2021)In analytical chemistry, multivariate calibration is applied when substituting a time-consuming reference measurement (based on e.g. chromatography) with a high-throughput measurement (based on e.g. vibrational spectroscopy). ... -
Diagnosing indirect relationships in multivariate calibration models
Eskildsen, Carl Emil Aae; Engelsen, Søren B.; Dankel, Elin Katinka; Solberg, Lars Erik; Næs, Tormod (Peer reviewed; Journal article, 2021)Problems concerning covariance among independent variables are well understood and dealt with by inverse regression methods like partial least squares regression. However, covariance between dependent variables has only ...
