Maximum–likelihood kernel density estimation in high–dimensional feature spaces
(North-West University, 2014)With the advent of the internet and advances in computing power, the collection of very large high-dimensional datasets has become feasible { understanding and modelling high-dimensional data has thus become a crucial ... -
A multi-wavelength study of a sample of galaxy clusters
(North-West University, 2012)In this dissertation we aim to perform a multi-wavelength analysis of galaxy clusters. We discuss various methods for clustering in order to determine physical parameters of galaxy clusters required for this type of study. ... -
Multiple imputation in the presence of a detection limit, with applications : an empirical approach
(2014)Scientists often encounter unobserved or missing measurements that are typically reported as less than a fixed detection limit. This especially occurs in the environmental sciences when detection of low exposures are not ...
