Multivariate linear QSPR/QSAR models: Rigorous evaluation of variable selection for PLS

open access: yesComputational and Structural Biotechnology Journal, 2013
Basic chemometric methods for making empirical regression models for QSPR/QSAR are briefly described from a user's point of view. Emphasis is given to PLS regression, simple variable selection and a careful and cautious evaluation of the performance of ...

Cross-validation

open access: yes, 2017
This text is a survey on cross-validation. We define all classical cross-validation procedures, and we study their properties for two different goals: estimating the risk of a given estimator, and selecting the best estimator among a given family. For the risk estimation problem, we compute the bias (which can also be corrected) and the variance of ...

Use of gene expression data for predicting continuous phenotypes for animal production and breeding

open access: yesAnimal, 2008
Traits such as disease resistance are costly to evaluate and slow to improve using current methods. Analysis of gene expression profiles (e.g. DNA microarrays) has potential for predicting such phenotypes and has been used in an analogous way to classify
