The application of multistate Markov models to HIV disease progression.
Survival analysis is a well developed area which explores time to single event analysis. In some cases, however, such methods may not adequately capture the disease process as the disease progression may involve ...
Modelling longitudinal binary disease outcome data including the effect of covariates and extra variability.
The current work deals with modelling longitudinal or repeated non-Gaussian measurements for a respiratory disease. The analysis of longitudinal data for non-Gaussian binary disease outcome data can broadly be modeled ...
Modelling longitudinally measured outcome HIV biomarkers with immuno genetic parameters.
According to the Joint United Nations Programme against HIV/AIDS 2009 AIDS epidemic update, there were a total of 33.3 million (31.4 million–35.3 million) people living with HIV worldwide in 2009. The majority of 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 ...
Modelling volatility in financial time series.
The objective of this dissertation is to model the volatility of financial time series data using ARCH, GARCH and stochastic volatility models. It is found that the ARCH and GARCH models are easy to fit compared to the ...

Estimation and analysis of measures of disease for HIV infection in childbearing women using serial seroprevalence data.
The prevalence and the incidence are two primary epidemiological parameters in infectious disease modelling. The incidence is also closely related to the force of infection or the hazard of infection in survival ...
Imputation for nonresponse using the Annual Financial Statistics Survey.
In this dissertation, we focus on the Annual Financial Statistics (AFS) survey. This is a survey conducted by Statistics South Africa, the national statistics office of South Africa. The main purpose of this survey is ...
