analysis of price indices of electrical appliances in South Africa is performed using monthly data from Statistics South Africa for the period January 1998 to December 2010, with 2005 as a base year. Time series analysis ...
The ever increasing number of students who drop out of university remains a challenge
for Higher Education administrators. In response to this, different studies have been
conducted globally in order to identify student ...
Introduction: The high number of variables from the 2009 General Household Survey is prohibitive to do holistic analysis of data due to high correlations that exist among many variables, making it virtually impractical to ...
This study presents the application of Direct and Indirect methods of Small AreaEstimation(SAE)techniques. Thestudyisaimedatestimatingthetrends and the proportions of households accessing water, sanitation, and electricity ...
This research study has demonstrated the complexity involved in complex survey sample design (CSSD). Furthermore the study has proposed methods to account for each step taken in sampling and at the estimation stage using ...
In spatial statistics, several methods have been developed to measure the extent
of local and global spatial dependence (clustering) in measured data across
areas in a region of research interest. These methods are now ...

The main purpose of modelling rare events such as heavy rainfall, heat waves,
wind speed, interest rate and many other rare events is to try and mitigate
the risk that might arise from these events. Heavy rainfall and ...
This thesis is based on application of frailty and copula models to under five
child mortality data set in South Africa. The main purpose of the study was to
apply sample splitting techniques in a survival analysis setting ...
Temperature extremes have a crucial impact on agricultural, economic, health
and energy sectors due to the occurrence of climate extreme events such as
heat waves and cold waves. Limpopo province is among the hottest ...
A number of previous research studies have investigated volatility and financial risks
in the ermeging markets. This dissertation investigates stock returns volatility and

Operations Research (OR) is a scientific method for developing quantitatively
well-grounded recommendations for decision making. While it is true that it
uses a variety of mathematical techniques, OR has a much broader ...
If study subjects are tracked long enough, it is a typical assumption in survival analysis that they will eventually experience the event of interest. However, that is not always the case. In reality, it is not uncommon ...
Statistics of extremes has seen much growth both in theory and application since its early theoretical developments almost a century ago in the 1920s and its first major applications to real-life problems pioneered by Emil ...
