(South African Statistical Association, 2015)Microarray experiments help scientists to study the expression level of thousands of genes simultaneously. These experiments have many design challenges, such as, for example, which mRNA samples should be co-hybridized ...
-
(Elsevier, 2024-09)The African continent reported the least number of COVID-19 cases and deaths of all the continents, although the exact reasons for this are still unclear. In addition, little is known about the immunological profiles ...
-
(BMC, 2021-05)BACKGROUND: Survival analysis is the most appropriate method of analysis for time-to-event data. The classical accelerated failure-time model is a more powerful and interpretable model than the Cox proportional hazards ...
-
(MDPI, 2022-05-23)Most analyses of spatial patterns of disease risk using health survey data fail to adequately account for the complex survey designs. Particularly, the survey sampling weights are often ignored in the analyses. Thus, the ...
-
(Elsevier, 2020-11)While activity-based travel demand generation has improved over the last few decades, the behavioural richness and intuitive interpretation remain challenging. This paper argues that it is essential to understand why people ...
-
(Wiley, 2019-06)AIM : To adapt the Youth‐Friendly Health Services‐World Health Organization+ questionnaire to suit the health needs of youth in the South African context, and estimate its psychometric properties. BACKGROUND : Youth‐friendly ...
-
(MDPI, 2022-11)Analysing autoregressive counts over time remains a relevant and evolving matter of interest, where oftentimes the assumption of normality is made for the error terms. In the case when data are discrete, the Poisson model ...
-
(Taylor and Francis, 2025)The Extended Cox model provides an alternative to the proportional hazard Cox model for modelling data including time-varying covariates. Incorporating time-varying covariates is particularly beneficial when dealing with ...
-
(CRIMSA, 2015)The reality of rape as a direct form of contact crime remains deeply entrenched in South African communities, despite numerous efforts from various governmental stakeholders to curb this heinous crime. The Criminal Law ...

-
(National Statistical Institute of Portugal, 2020-07)This paper paves the way when the assumption of normality is challenged within the wireless communications systems arena. Innovative results pertaining to the distributions of quadratic forms and their associated eigenvalue ...
-
(Elsevier, 2016-09)Consistent associations have been found between advanced paternal age and an increased risk of psychiatric disorders, such as schizophrenia in their offspring. This increase appears to be linear as paternal age increases. ...
-
(MDPI, 2021-06-25)Entropy is a functional of probability and is a measurement of information contained in a system; however, the practical problem of estimating entropy in applied settings remains a challenging and relevant problem. The ...
-
(Springer, 2024-11)The search and construction of appropriate and flexible models for describing and modelling empirical data sets incongruent with normality retains a sustained interest. This paper focuses on proposing flexible skew Laplace ...
-
(Springer, 2017-03)High levels of crime in South Africa and the resulting court cases requiring bite mark evidence have necessitated continuous research into the prevalence and interrelationship of recognisable dental features present in ...
-
(Media 24 & South African Orthopaedic Association, 2011)The publication of our long-term hip replacement follow-up study computer analysis has clearly demonstrated the association between polyethylene (polyethylene/UHMWPE) wear on the one hand and pain, interface widening and ...
-
(Elsevier, 2024-06)INTRODUCTION : Anterior orthopaedic approaches, much like the Modified Stoppa approach, target fractures of the anterior column of the pelvis and acetabulum. The approach is described as a minimally invasive technique ...
-
(Elsevier, 2022-05-06)PURPOSE : Several surgical and clinical procedures are performed in the area of the medial compartment of the thigh. This places the obturator nerve and its branches in potential danger of injury. This study aimed to ...
-
(BMJ Publishing Group, 2022-03)INTRODUCTION: Few interventions exist to address the high burden of stillbirths in apparently healthy pregnant women in low- and middle-income countries (LMICs). To establish whether a trial on the impact of routine Doppler ...
-
(Health and Medical Publishing Group, 2018)BACKGROUND : Anterior cruciate ligament (ACL) injuries are common among athletes and the general public. These injuries may lead to significant absence from all activities with associated financial and social burdens for ...
