Nonlinear mixed-effects models for multi-variate longitudinal data with application to HIV disease dynamics.
(2014)The motivation for the study of nonlinear mixed-effects models is due to the growing interest in the estimation of parameters in HIV disease dynamical models using real multivariate longitudinal data with varying degrees ... -
Nonlinear models for neural networks.
(2000)The most commonly used applications of hidden-layer feed forward neural networks are to fit curves to regression data or to provide a surface from which a classification rule can be found. From a statistical viewpoint, the ... -
Numerical study of convective fluid flow in porous and non-porous media.
(2015)Abstract available in PDF file. -
On the geometry of locally conformal almost cosymplectic manifolds and 2-order Lagrange space.
(2017)Abstract available in pdf. -
A perspective on incomplete data in longitudinal multi-arm clinical trials, with emphasis on pattern-mixture-model based methodology.
(2014)Missing data are common in longitudinal clinical trials. Rubin described three different missing data mechanisms based on the level of dependence between the missing data process and the measurement process. These are ... -
Prevalence and risk factors associated with malaria infection in children under the age of fourteen years in Kenya.
(2017)Despite various efforts by multilateral agencies and governments to prevent, control and eliminate malaria, it continues to be a major plague with more than 300 million at risk of infection worldwide. In Kenya, it is still ... -
Prevalence and risk factors of malaria in children under the age of five years old in Uganda.
(2015)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 ... -
A review of methods for modelling both Gaussian and Non-Gaussian longitudinal data with application.
The study of longitudinal data plays an integral role in medicine, epidemiology, social science, biomedical and health sciences research where repeated measurements are obtained over time for each individual. Generally, ... -
The role of immune-genetic factors in modelling longitudinally measured HIV bio-markers including the handling of missing data.
(2013)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 ... -
Sexual debut: an analysis of the birth to twenty data.
(2015)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 ... -
Spatial analysis and efficiency of systematic designs in intercropping experiments.
(2002)In studies involving intercropping plant populations, the main interest is to locate the position of the maximum response or to study the response pattern. Such studies normally require many plant population levels. Thus, ... -
Spatial and spatio-temporal modeling and mapping of self-reported health among individuals between the ages of 15-49 years in South Africa.
(2019)Self-reported health has been commonly used as a measure of individuals health in public health studies. Health presents a complete physical, emotional, and social well-being. It also plays an important role in the ... -
Spatio-temporal modelling and mapping of malaria in Angola.
(2017)About half of the world's population is at risk of contracting malaria. The growing number of malaria cases and deaths due to this disease in Africa has become a major challenge to public health care sector. Malaria is ... -
Special topics in probabilistic exchangeability and its applications.
(2017)This thesis evolves around a probabilistic concept called exchangeability and its generalised forms. It is aimed at exploring connections between exchangeability and other sub-areas in mathematical statistics. These ... -
The statistical analyses of a complex survey of banana pests and diseases in Uganda.
(1999)No abstract available. -
A statistical analysis of dissolving timber pulp properties using linear mixed models.
(2017)The main focus of the study was to understand the behaviour of seven timber genotypes based on seven chemical properties observed during the chemical pulping process with the prime objective of developing methods of grouping ... -
Statistical analysis of the attitudes towards blood donation and transfusion in Mali.
(2016)The demand for blood transfusion in Mali is high, because of the high prevalence of anemia, which is mostly caused by malaria, malnutrition and pregnancy-related complications. In this study a classic KNOWLEDGE, ATTITUDE ... -
Statistical analysis of the incidence and mortality of African horse sickness in South Africa.
(2011)No abstract available. -
Statistical and mathematical modelling of HIV and AIDS, effect of reverse transcriptase inhibitors and causal inference for HIV mortality.
(2010)The HIV and AIDS epidemic has remained one of the leading causes of death in the world and has been destructive in Africa with Sub-Saharan Africa remaining the epidemiological locus of the epidemic. HIV and AIDS ... -
Statistical approaches for handling longitudinal and cross sectional discrete data with missing values focusing on multiple imputation and probability weighting.
