Nonparametric smoothing in extreme value theory
… and scale parameters of the generalized extreme value distribution and the distribution of the r largest order statistics. Estimation is performed by implementing a Fisher scoring algorithm to maximize the penalized log-likelihood function. The approach provides a flexible framework for exploring …

Comparison of Bayes' and minimum variance unbiased estimators of reliability in the extreme value life testing model
… of estimators for reliability using the extreme value distribution as the life-testing model. First the unbiased minimum variance estimator is derived. Then the Bayes' estimators for the uniform, exponential, and inverted gamma prior distributions are obtained, and these results are extended to a …

Estudo das características estocásticas do roll paramétrico
… been used for fitting the Generalized Extreme Value Distribution (GEVD) and the Generalized Pareto Distribution (GPD). Then, using the fitted GEVD, the return period and the time between events for roll motions have been computed for two wave conditions.

A study of some life testing distributions
… The first article considers a new life-testing distribution which has the property of possessing a failure rate function which can be U-shaped or exponentially increasing depending on the value of the shape parameter. In addition, this article considers generalized least squares type estimators …

Response Surface Method for Time-Variant Reliability Analysis
… conditional upon the uncertain system parameter values is assumed to follow an extreme value distribution, the parameters of which are fitted by the response surface models. The fast integration scheme provides a formulation of a limit state function which incorporates this information. The …

The impact of estimation frequency on Value at Risk (VaR) and Expected Shortfall (ES) forecasts: an empirical study on conditional extreme value models
… market events which occur in the tails of a distribution. The extreme events occur with a very low probability, but with significant consequences, which is what makes them of interest. In this study 20 years of data from both the S&P 500 and the JSE All Share index have been used. An extreme …

Towards a volumetric city
… revealing the differences in real-estate value across the section. The thesis takes the opportunity to reinvent a new ground - a datum - which reorganizes the commercial value distribution, reinvents generic typologies and at the same time liberates the natural ground. New cityscapes can …

Free-space phase-fading MIMO: system model and capacity analysis
… its capacity is determined by singular eigenvalue distribution of the random correlation matrix corresponding to channel transmit matrix. Firstly, for proposed Free-Space MIMO system, the asymptotic analysis was performed for the ergodic capacity with respect to the infinite number of …

Cloud based sensor analysis for customer-specific residual value estimation for end-of-life product recovery
… steps is to estimate the product's residual value, primarily on the basis of age and a cursory visual inspection. However, there is a high degree of variability in actual value, even for products of the same age. This is due to the variability of environmental and use conditions to which the …

Future changes in extreme rainfall events and circulation patterns over southern Africa
… basis. The second approach is based on extreme value theory. Here, the Generalized Extreme Value distribution (GEV) is fitted to annual maxima precipitation by a L-moments method. The 20-year return values are analyzed for present and future climate conditions. The physical drivers of the …

Value accruing to Zambia’s bean supply chain participants
The purpose of this thesis was to estimate the value accruing to Zambian bean supply chain participants with the view to showing that value at the different stages is a function of the value addition and risk incurred at those stages. The data used in the study came from two different surveys done …
