Second-order multivariate calibration with the extended bilinear model: Effect of initialization, constraints, and composition of the calibration set on the extent of rotational ambiguity
(John Wiley & Sons Ltd, 2020-03-15)
Extended bilinear modeling is popular in second-order multivariate calibration, particularly when the matrix data for each sample are of chromatographic origin. Since elution time profiles vary across samples, in both shape ...
Support vector regression for functional data in multivariate calibration problems

Calibration uncertainty estimation for internal aerodynamic balance
(2008-12-01)
Aerodynamic balances are employed in wind tunnels to estimate the forces and moments acting on the model under test. This paper proposes a methodology for the assessment of uncertainty in the calibration of an internal ...

Deltamethrin determination in natural water samples via photochemically-induced fluorescence coupled to third-order multivariate calibration
(Elsevier, 2020)
In this work, an analytical method for deltamethrin determination in natural waters based on photochemicallyinduced fluorescence coupled to third-order/four-way calibration was evaluated and compared with secondorder/three-way ...
Error Covariance Penalized Regression: A novel multivariate model combining penalized regression with multivariate error structure
(Elsevier Science, 2018-06)
A new multivariate regression model, named Error Covariance Penalized Regression (ECPR) is presented. Following a penalized regression strategy, the proposed model incorporates information about the measurement error ...
