Modelling CD4+ count over time in HIV positive patients initiated on HAART in South Africa using linear mixed models.
HIV is among the highly infectious and pathogenic diseases with a high mortality rate. The spread of HIV is in uenced by several individual based epidemiological factors such as age, gender, mobility, sexual partner pro ...
Forecasting the monthly electricity consumption of municipalities in KwaZulu-Natal.
Eskom is the major electricity supplier in South Africa and medium term forecasting within the company is a critical activity to ensure that enough electricity is generated to support the country's growth, that the networks ...
Inference from finite population sampling : a unified approach.
In this thesis, we have considered the inference aspects of sampling from a finite population. There are significant differences between traditional statistical inference and finite population sampling inference. In the ...
The role of immune-genetic factors in modelling longitudinally measured HIV bio-markers including the handling of missing data.
Since the discovery of AIDS among the gay men in 1981 in the United States of America, it has become a major world pandemic with over 40 million individuals infected world wide. According to the Joint United Nations ...
Multivariate time series modelling.
This research is based on a detailed description of model building for multivariate time series models. Under the assumption of stationarity, identification, estimation of the parameters and diagnostic checking for the ...
Completion of an incomplete market by quadratic variation assets.
It is well known that the general geometric L´evy market models are incomplete, except for the geometric Brownian and the geometric Poissonian, but such a market can be completed by enlarging it with power-jump assets ...
Bayesian hierarchical spatial and spatio-temporal modeling and mapping of tuberculosis in Kenya.
Global spread of infectious disease threatens the well-being of human, domestic, and wildlife health. A proper understanding of global distribution of these diseases is an important part of disease management and policy ...

Multilevel modelling of HIV in Swaziland using frequentist and Bayesian approaches.
Multilevel models account for different levels of aggregation that may be present in the data. Researchers are sometimes faced with the task of analysing data that are collected at different levels such that attributes ...
Likelihood based statistical methods for estimating HIV incidence rate.
Estimation of current levels of human immunodeficiency virus (HIV) incidence is essential for monitoring the impact of an epidemic, determining public health priorities, assessing the impact of interventions and for ...
