Grobler, Roger R.
(University of Pretoria, 2003-05-15)
Property insurance covers policyholders against losses arising out of a wide range of occurrences. Premiums are calculated by taking into account estimates of the frequency and the severity of the losses. Estimating the ...

Messerschmidt, Reinhardt
(University of Pretoria, 2007-02-20)
Hattendorff's theorem on the zero means and uncorrelatedness of losses in disjoint time periods on a life insurance policy is derived for payment streams, discount functions and time periods that are all stochastic. Thiele's ...

Du Plessis, Hendrik Lourens Marthinus
(Cambridge University Press, 2011-08-31)
This paper analyses the driving forces behind the willingness of South African courts to hear
actuarial expert testimony in even the most simple of cases, in contrast to the more circumspect
approach of the English courts, ...

De Witt, Corn e Juan
(University of Pretoria, 2013)
This study provides systematic analysis of points of structural change in probability distributions.
In observed frequency data of earthquakes, such a threshold exists due to the non-detection of events
below a certain ...

Smith, Matthew Lee
(University of Pretoria, 2014)
The modelling technique known as Artificial Neural Networks (ANNs) is investigated. ANNs have the ability to detect and project non-linear relationships between variables. Further, they can adapt in dynamically changing ...

Pretorius, Samantha
(University of Pretoria, 2014-04-30)
The research attempts to resolve which method of estimation is the most consistent for the parameters of the earthquake model, and how these different methods of estimation, as well as other changes, in the earthquake model ...

Smith, M.L. (Mattie); Beyers, Frederik Johannes Conradie; De Villiers, Johan Pieter
(Actuarial Society of South Africa, 2016)
No analytic procedures currently exist for determining optimal artificial neural network structures and
parameters for any given application. Traditionally, when artificial neural networks have been applied
to financial ...

Flint, Emlyn James; Mare, Eben
(Actuarial Society of South Africa, 2017)
In this research we describe how forward-looking information on the statistical properties of an asset
can be extracted directly from options market data and demonstrate how this can be practically applied
to portfolio ...

Yang, Jack Chao
(University of Pretoria, 2018)
The study aims to quantitatively assess the extent to which sovereign ratings could be explained by a set of economic variables. A wide variety of factors could potentially bias a credit rating agency’s decision. The ...

Van Appel, Vaughan; Mare, Eben
(Operations Research Society of South Africa, 2018-11-04)
Recently, Ross derived a theorem, namely the “Recovery Theorem”, that allows for the recovery of the pricing kernel and real-world asset distribution, under particular assumptions, from a forward-looking risk neutral ...

Smart, Sally-Anne
(University of Pretoria, 2019)
Social unrest, terrorism and other forms of political violence events are highly unpredictable. These events are driven by human intent and intelligence, both of which are extremely difficult to model accurately. This has ...

Walters, Nadine Mari
(University of Pretoria, 2019)
We introduce new tiered bank network structures, allowing for many di erent bank sizes,
and compare risk propagation in these structures with the well-known Erd˝os-R´enyi, assortative
and disassortative structures. The ...

Flint, Emlyn James
(University of Pretoria, 2019)
The modern quantitative portfolio manager is the quintessential “jack of all trades”. Not only do they need to be an expert in the specific area of portfolio management, they also need to have a thorough understanding of ...

(World Scientific Publishing, 2019-03)
We consider the fraction of nodes that default in large, stochastic, inhomogeneous financial networks following an initial shock to the system. Results for deterministic sequences of networks are generalized to stochastic ...

(South African Statistical Association, 2020)
The forward-looking nature of option prices provides an appealing way to extract risk measures. In this paper, we extract forecast densities from option prices that can be used in forecasting risk measures. More specifically, ...
