Finally, the energetic value of the tail may depend on size. Influence of size, loss of tail, and burst speed on risk of predation in the banded gecko [ClickPress, Wed Sep 04 2019] Fact.MR has published a new research report on global automotive tail light market sizes, upcoming industry...
for all Borel sets that are bounded away from 0 and such that (see Definition 2.1). This allows us to conclude that for continuous and 1-homogeneous functions (Proposition 2.5). Therefore, if h is such a risk functional, we readily obtain an asymptotic approximation of the probability of an...
2.1. Measuring the tail risk impact of ETM prices on commodity prices We assess the impact of extreme upward and downward movements in ETM prices on the expected value and on the variance of commodity price returns as follows. Let rETM be ETM price returns, and let rETMα and rETMβ be...
To address this type of decision-making issue, this paper introduces the definition of value at risk (VaR), which is a famous term in the financial field, and the probabilistic hesitant fuzzy element (PHFE), which is a general hesitant fuzzy element (HFE) and has recently become a popular...

We argue that a natural and empirically correct framework for assessing (and managing) the real risk of pandemics is provided by extreme value theory (EVT), an approach that has historically been developed to treat phenomena in which extremes (maxima or minima) and not averages play the role ...
One approach consists in seeking for the minimum of the tail of the Probability Distribution Function (PDF) of the cost functional at some large fixed value. Another option suggests to minimize the expectation value of the cost functional under constraint on the value of the PDF tail. Under ...

The value of tail dependence is essentially calculated as a limit, so we can avoid the discretionary choice of a threshold as in the definition of downside beta. Besides, the tail dependence can be very easily calculated using the sound Copula functions. Copula is a function that incorporates ...
