THE DANGERS OF EXTREMES [PDF]

open access: yesInternational Journal of Modern Physics D, 2010
While extreme black hole space–times with smooth horizons are known at the level of mathematics, we argue that the horizons of physical extreme black holes are effectively singular. Test particles encounter a singularity the moment they cross the horizon, and only objects with significant back-reaction can fall across a smooth (now non-extreme ...

Which Extreme Values Are Really Extreme? [PDF]

open access: yesJournal of Financial Econometrics, 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. The threshold is the order statistic that minimizes a Kolmogorov-Smirnov statistic between the empirical distribution of the ...
