An assessment of modified systematic sampling designs in the presence of linear trend.
(2017)Sampling is used to estimate population parameters, as it is usually impossible to study a whole population, due to time and budget restrictions. There are various sampling designs to address this issue and this thesis ... -
Count data modelling application.
(2019)The rapid increase of total children ever born without a proportionate growth in the Nigerian economy has been a concern and making prediction with count data requires applying appropriate regression model.. As count data ... -
Imputation for nonresponse using the Annual Financial Statistics Survey.
(2011)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 ... -
Inference from finite population sampling : a unified approach.
(2007)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 management of missing categorical data : comparison of multiple imputation and subset correspondence analysis.
(2015)Missing data is a common problem in research and the manner in which this ‘missingness’ is managed, is crucial to the validity of analysis outcomes. This study illustrates the use of two diverse methods to handle, in ... -
Modelling residential electricity usage within the eThekwini Municipal Area.
(2014)In this study we use linear mixed models to model residential electricity consumption within the eThekwini municipal area. Utilities around South Africa are required to estimate monthly electricity consumptions for each ... -
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 ... -
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 modelling and spatial mapping of crime in South Africa.
(2016)This research investigates factors related to crime rates for the 2013/2014 South African Crime Survey. The survey provides personal information and crime related experiences for all members of the 25 605 households that ... -
Systematic sampling from finite populations.
(2013)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 ...
