2. 1. OnPLS : Orthogonal projections to latent structures in multiblock and path model data analysis

   Author : Tommy Löfstedt; Johan Trygg; Michael Peolsson; Michel Tenenhaus; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; OnPLS; OPLS; O2PLS; PLS; Multivariate analysis; Multiblock and path modelling; Chemometrics;

   Abstract : The amounts of data collected from each sample of e.g. chemical or biological materials have increased by orders of magnitude since the beginning of the 20th century. Furthermore, the number of ways to collect data from observations is also increasing. READ MORE

4. 2. Novel variable influence on projection (VIP) methods in OPLS, O2PLS, and OnPLS models for single- and multi-block variable selection : VIPOPLS, VIPO2PLS, and MB-VIOP methods

   Author : Beatriz Galindo-Prieto; Johan Trygg; Lennart Eriksson; Paul Geladi; Olav M. Kvalheim; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Variable influence on projection; VIP; MB-VIOP; orthogonal projections to latent structures; OPLS; O2PLS; OnPLS; variable selection; variable importance in multiblock regression; Computer Science; datalogi;

   Abstract : Multivariate and multiblock data analysis involves useful methodologies for analyzing large data sets in chemistry, biology, psychology, economics, sensory science, and industrial processes; among these methodologies, partial least squares (PLS) and orthogonal projections to latent structures (OPLS®) have become popular. Due to the increasingly computerized instrumentation, a data set can consist of thousands of input variables which contain latent information valuable for research and industrial purposes. READ MORE

5. 3. Multivariate integration and visualization of multiblock data in chemical and biological applications

6. 4. Combined profiling in aspen : a systems biology approach

   Author : Ogonna Obudulu; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : This thesis presents efficient systems biology modelling strategies for integrating complex multi-platform datasets in order to increase our understanding of stress biology, wood formation and secondary cell wall formation in Populus trees and connected responses to perturbations in organisms, particularly aspen. It is based on studies reported in four appended papers, designated Papers I-IV. READ MORE
