An ‘apples to apples’ comparison of various tests for exponentiality
(Springer, 2017)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 ... -
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 procedures for online monitoring of changes in autoregressive models
(Taylor & Francis, 2016)We compare the behavior of several bootstrap procedures for monitoring changes in the error distribution of autoregressive time series. The proposed procedures are designed to control the overall significance level and ... -
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 ... -
Modified tests for exponentiality in the presence of Type II right censored data
(Wiley, 2019)The exponential distribution is one of the most popular choices of model, especially in survival analysis and reliability theory. Typically, to test the hypothesis that the underlying distribution of lifetimes are exponentially ... -
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 ... -
A new approach to function-based hypothesis testing in location-scale families
(Taylor & Francis, 2013)Motivated by two applications in the mining industry, we introduce a new approach to testing the hypothesis that two-sampled distributions are simply location and scale changes of one another. The test, applicable to both ... -
New semiparametric and nonparametric bootstrap tests for Spearman's rho
(SASA, 2011)In this paper we propose two bootstrap-based tests for Spearman's rho. The first is a semiparametric test based on copulas, while the second is a nonparametric test. The efficiency of the tests are investigated by means ...
