Malaria is considered to be one of the main global health problems, with it causing close to a million deaths each year. Ninety percent of these deaths occur in Sub- Saharan Africa and 70% are of children under the age ...
Bayesian spatial models with application to HIV, TB and STI modeling in Kenya.
This dissertation is concerned with developing and extending statistical models in the area of spatial modeling with particular interest towards application to HIV, TB and HSV-2 data. Hierarchical spatial modeling is a ...
The application of classification techniques in modelling credit risk.
The aim of this dissertation is to examine the use of classification techniques to model credit risk through a practice known as credit scoring. In particular, the focus is on one parametric class of classification techniques ...
Mean-square fractional calculus and some applications.
The fractional calculus of deterministic functions is well known and widely used. Mean-square calculus is a calculus that is suitable for use when dealing with second-order stochastic processes. In this dissertation we ...
Systematic sampling from finite populations.
The impossibility to reach an entire population, owing to time and budget constraints, results in the need for sampling to estimate population parameters. There are various methods of sampling and this thesis deals with ...
The modelling of African animal trypanosomiasis in KwaZulu-Natal, South Africa.
African animal trypanosomiasis (AAT), restricted to parts of the KwaZulu-Natal Province, is a disease which contributes signi cantly to the disease burden of cattle. Drug resistance is a constraint and dipping of cattle ...

Sexual debut: an analysis of the birth to twenty data.
According to the literature, it is widely accepted that the early timing of first sex among adolescents is related to long-term health effects and current and future risky sexual behaviour (Sandfort et al., 2008). Despite ...
Modeling financial data using the multivariate generalized hyperbolic distribution and copula.
Financial data usually possess some characteristics, such as volatility clustering, asymmetry, heavy and semi-heavy tails thus, making it difficult, if not impossible, to use Normal distribution to model them. Statistical ...
Modelling volatility in stock exchange data : a case study of three Johannesburg Stock Exchange (JSE) companies.
For investors and policy makers such as governments, the uncertainty of returns on investments is a major problem. The aim of this paper is to study volatility models for financial data for both univariate and multivariate ...
