Heavy operators and hydrodynamic tails [PDF]

open access: yesSciPost Physics, 2020
The late time physics of interacting QFTs at finite temperature is controlled by hydrodynamics. For CFTs this implies that heavy operators -- which are generically expected to create thermal states -- can be studied semiclassically.

Linear Regression for Heavy Tails [PDF]

open access: yesRisks, 2018
There exist several estimators of the regression line in the simple linear regression: Least Squares, Least Absolute Deviation, Right Median, Theil–Sen, Weighted Balance, and Least Trimmed Squares.

Understanding Heavy Tails in a Bounded World or, is a Truncated Heavy Tail Heavy or Not? [PDF]

open access: yesStochastic Models, 2012
We address the important question of the extent to which random variables and vectors with truncated power tails retain the characteristic features of random variables and vectors with power tails. We define two truncation regimes, soft truncation regime and hard truncation regime, and show that, in the soft truncation regime, truncated power tails ...

Heavy tails and pruning in programmable photonic circuits for universal unitaries [PDF]

open access: yesNature Communications, 2023
Authors model programmable photonic circuits targeting universal unitaries and verify that a type of unit rotation operator has a heavy-tailed distribution.

Top Incomes, Heavy Tails, and Rank-Size Regressions

open access: yesEconometrics, 2018
In economics, rank-size regressions provide popular estimators of tail exponents of heavy-tailed distributions. We discuss the properties of this approach when the tail of the distribution is regularly varying rather than strictly Pareto.

The Asymptotics of Moments for the Remaining Time of Heavy-Tail Distributions

open access: yesComputer Sciences & Mathematics Forum, 2023
Recent mathematical models of reliability computer systems and telecommunication networks are based on distributions with heavy tails. This paper falls into the category of exploring the classical models with heavy tails: Gnedenko–Weibull, Burr ...

Assessment of temporal change in the tails of probability distribution of daily precipitation over India due to climatic shift in the 1970s

open access: yesJournal of Water and Climate Change, 2021
Daily precipitation extremes are crucial in the hydrological design of major water control structures and are expected to show a changing tendency over time due to climate change.

Estimation of the value-at-risk parameter: Econometric analysis and the extreme value theory approach [PDF]

open access: yesEkonomski Anali, 2006
In this paper different aspects of value-at-risk estimation are considered. Daily returns of CISCO, INTEL and NASDAQ stock indices are analyzed for period: September 1996 - September 2006. Methods that incorporate time varying variability and heavy tails

Minimum of heavy-tailed random variables is not heavy tailed

open access: yesAIMS Mathematics, 2023
<abstract><p>By constructing an appropriate example, we show that the class of heavy-tailed distributions is not closed under minimum. We provide two independent heavy-tailed random variables, such that their minimum is not heavy tailed. In addition, we establish a few properties of the distributions considered in the example.</p></
