Bootstrap bandwidth selection in kernel hazard rate estimation
(North-West University, 2011)The purpose of this study is to thoroughly discuss kernel hazard function estimation, both in the complete sample case as well as in the presence of random right censoring. Most of the focus is on the very important task ... -
Bootstrap unit root tests : a Monte Carlo investigation
(North-West University, 2018)In this study we investigate the finite-sample performance of some of the existing bootstrap unit root tests in terms of size and power by means of an extensive Monte Carlo study. Comparing the performance of these bootstrap ... -
Goodness-of-fit testing in survival models
(North-West University (South Africa), 2020)The statistical analysis of lifetime data is an important topic in many areas, such as the biomedical and engineering sciences. The main objective in many of these studies is to examine the relationship between lifetimes ... -
Investigation into linear regression influence measure diagnostics and bootstrap-based inferential techniques
(North-West University (South Africa)North-West University, 2020)Since extreme or influential observations drastically affect the fit of regression models, their detection plays a big role in regression model fi tting. Many traditional diagnostic techniques employ single-case deletion ... -
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 ... -
An objective comparison between various goodness-of-fit tests for exponentiality
(North-West University, 2018)The exponential distribution is a popular model both in practice and in theoretical work. As a result, a multitude of tests based on varied characterisations have been developed for testing the hypothesis that observed ... -
On a new method for constructing bootstrap confidence bounds
(North-West University (South Africa), Potchefstroom Campus, 2017)It is well-known that the standard methods for constructing bootstrap confidence bounds or intervals are in many situations not sufficiently accurate, that is, coverage probabilities converge to the nominal level at ...
