Self-modeling Regression for Multivariate Curve Data
We present self-modeling regression models for flexible nonparametric modeling of multiple outcomes measured longitudinally. Based on penalized regression splines, the models borrow strength across multiple outcomes by specifying a global time profile, thereby yielding a means of dimension reduction and estimates of trend more precise than those based on univariate regressions. The proposed mod...
متن کاملA two-step ICT process for solvatochromic betaine pyridinium revealed by ultrafast spectroscopy, multivariate curve resolution, and TDDFT calculations.
This work deals with the photophysics of a pyridinium betaine, 2-pyridin-1-yl-1H-benzimidazole (SBPa), based on a combination of steady-state, femtosecond photoionization (gas phase) and femtosecond transient absorption (solution) spectroscopic measurements, supported by (LR)-PCM-(TD)DFT calculations. Preliminary and new electrochemical results have revealed a strongly negative solvatochromic c...
متن کاملIntegration of Multivariate Statistical Process Control and Engineering Process Control
Two independent methods for improving quality are engineering process control (EPC) and statistical process control (SPC). The first method tries to minimize variability by handling process variables so as to keep the outputs of the process on target. While the latter method, SPC does the same basic task of minimizing variability by supervising and eradicating the assignable causes of variation...
متن کاملSpatial extensions to self - modeling curve resolution
Through recent developments in data acquisition procedures, large amounts of spatially resolved hyperspectral data have become available. However, the development of adequate data analysis methods which exploit the intrinsic spatial information lags behind. We propose a self-modeling curve resolution (SMCR) algorithm which takes spatial relationships into account. This is accomplished by enforc...
متن کاملNon-linear multivariate curve resolution analysis of voltammetric pH titrations.
A new chemometric approach is put forward, dealing with the non-linear behaviour observed in the multivariate curve resolution (MCR) analysis of certain overlapping voltammetric signals obtained in titrations of metal complexes where pH is progressively changed. In such cases, non-reversible reduction signals move along the potential axis as a consequence of the involvement of H(+)-ions in the ...
