Which Extreme Values Are Really Extreme? [PDF]

open access: yes, 2004
We define the extreme values of any random sample of size n from a distribution function F as the observations exceeding a threshold and following a type of generalized Pareto distribution (GPD) involving the tail index of F.

Modelling Financial Risk in the South African Stock Market: An Application of the Generalised Extreme Value Distribution (GEVD)

open access: yesEconometric Research in Finance
This study analyses the return characteristics of the South African Industrial Index (J520) and South African Financial Index (J580) using the Generalized Extreme Value Distribution (GEVD) to estimate return levels, Value-at-Risk (VaR) and Expected ...

Comparative assessment of crystallographic and cryo‐EM models in the Protein Data Bank

open access: yesFEBS Open Bio, EarlyView.
Raw data obtained by X‐ray crystallography or cryo‐EM result in experimental maps, ultimately fitted by atomic models. Although the physical principles are different, the final results can be viewed, compared, and evaluated in the same way. With cryogenic electron microscopy (cryo‐EM) on track to surpass X‐ray crystallography as the preferred method ...

Future changes in the mean and extreme sea surface winds over the East Asian marginal seas projected by regional climate models

open access: yes, 2019
Sea surface wind, especially extreme winds, plays a crucial role in coastal safety including flooding and coastal erosion mainly by changing sea level and ocean wind waves, and the regional characteristics of sea surface wind can be in uenced by global ...

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

open access: yesFEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

Filtered Extreme Value Theory for Value-At-Risk Estimation [PDF]

open access: yes
Extreme returns in stock returns need to be captured for a successful risk management function to estimate unexpected loss in portfolio. Traditional value-at-risk models based on parametric models are not able to capture the extremes in emerging markets ...
