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 ... -
Inference for linear regression models in the presence of heteroskedasticity
(North-West University (South Africa), Potchefstroom Campus, 2016)The linear regression model is a highly versatile tool with which one can model a response variable in terms of one or more predictor variables. The classical linear model is based on six primary theoretical assumptions. ... -
Investigating the effect of restricting residuals in bootstrap based hypothesis testing
(North-West University, 2018)In this dissertation, model-based bootstrap methods for testing the hypothesis for the population mean, population variance and regression model coe cient parameters are discussed by considering eight di erent ways to ... -
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 ... -
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 testing the assumption of the Pareto type I distribution
(North-West University (South Africa), 2023)The Pareto distribution is a popular model in economics, finance and actuarial sciences. Consequently, a number of goodness-of-fit tests, based on diverse characteristics, have been developed to test the goodness- of-fit ...
