Assessing Multivariate Heritability through Nonparametric Methods
… of traits can be estimated. Due to the multivariate nature of many traits, such as size and shape, computation of heritability can be difficult. Also, assessment of the variation of the heritability estimate is extremely difficult. This study uses nonparametric methods, namely the …

Systems biology of breast cancer
… a time. Microarrays with their high data volume, multivariate nature and non-linearity pose challenges for analysing using conventional statistical approaches. To combat these challenges, computational researchers have developed machine learning approaches such as Artificial Neural Networks …

Multivariate Methods for the Study of Beta-lactam Resistance in Streptococci
… they have also highlighted its complex, multivariate nature, involving correlations both within and between drug classes. These studies have driven the development of methods for the analysis of genotypes, but tools for the study of resistance phenotypes have remained limited, …

Screening experiments using supersaturated designs with application to industry
… features of the experiment include the multivariate nature of the response and the fact that factor levels cannot be set directly. A two-stage linear mixed effect model is applied, with principal components analysis used for the first stage models. A novel method for finding follow-up …

Functional linear regression on Namibian and South African data
… challenges present themselves such as the multivariate nature of the data. Functional data analysis was used in this project to display the data so as to highlight various characteristics while allowing us to study important sources of pattern and variation among the data. Functional data …

A Visualization Framework for SiLK Data exploration and Scan Detection
… to this protocol's traffic, rather than on the multivariate nature of network security data in general, and the fact that forensic analysis, in order to be fast and effective, has to take into consideration different parameters for each protocol. In this thesis, we bring together two powerful …

Computational Modelling of Nanoscale Interactions for Nanophotonics and Biosensing
… molecules from the biosensor signals due to the multivariate nature of the problem. The spectral signals encode information about the species, charge, and conformation of the target molecule, as well as the location of the molecule within the biosensing field. This thesis explores the …

A partial dependence factorial analysis to deal with selection bias in observational studis
… allows measuring and testing in an automatic and multivariate way the presence of selection bias. The approach involves the construction of a multi-dimensional conditional space of the X matrix in which the bias associated with the treatment assignment has been eliminated. Specifically, we propose …

The distinct contributions of cardiovascular risk factors to cognitive ageing
… These chapters use interdisciplinary and multivariate statistical analyses, applied to a large cohort of healthy adults (n=708, 18-88 years). Chapter 3 investigates whether multiple discrete vascular factors make distinct contributions to cognition. It shows unique and additive …

The Development of Computational High-Throughput Approaches for Screening Metal-Organic Frameworks in Adsorptive Separation Applications
… have been synthesised so far, as well as the multivariate nature of that performance criteria that need to be considered when selecting or designing an optimal adsorbent for a separation process. However, it is infeasible to assess all the potential materials experimentally to identify the …

Uncovering strata: an investigation into the graphic innovations of geologist Henry T. De la Beche
… Golden Age of Geology (1788-1840) revealed the nature and progression of graphic representation at the dawning of geology as a science. Exhaustive sampling of geology texts published in the period of focus proceeded until saturation was achieved. Qualitative analysis and evaluation of early …
