Option-implied information and predictability of extreme returns : [Version 28 Januar 2013] [PDF]

open access: yes, 2012
We study whether prices of traded options contain information about future extreme market events. Our option-implied conditional expectation of market loss due to tail events, or tail loss measure, predicts future market returns, magnitude, and ...

A Renewal Shot Noise Process with Subexponential Shot Marks

open access: yesRisks, 2019
We investigate a shot noise process with subexponential shot marks occurring at renewal epochs. Our main result is a precise asymptotic formula for its tail probability.

One small step for an inflaton, one giant leap for inflation: A novel non-Gaussian tail and primordial black holes

open access: yesPhysics Letters B, 2022
We report a novel prediction from single-field inflation that even a tiny step in the inflaton potential can change our perception of primordial non-Gaussianities of the curvature perturbation. Our analysis focuses on the tail of probability distribution

The probability density function tail of the Kardar-Parisi-Zhang equation in the strongly non-linear regime [PDF]

open access: yes, 2016
An analytical derivation of the probability density function (PDF) tail describing the strongly correlated interface growth governed by the nonlinear Kardar-Parisi-Zhang equation is provided. The PDF tail exactly coincides with a Tracy-Widom distribution

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.

Normal Inverse Gaussian Approximation for Arrival Time Difference in Flow-Induced Molecular Communications [PDF]

open access: yes, 2018
In this paper, we consider molecular communications in one-dimensional flow-induced diffusion channels with a perfectly absorbing receiver. In such channels, the random propagation delay until the molecules are absorbed follows an inverse Gaussian (IG ...

On Tail Probabilities of Continuous Probability Distributions with Heavy Tails [PDF]

open access: yesKorean Journal of Applied Statistics, 2013
Abstract The paper examines several classes of probability distributions with heavy tails. An (asymptotic) expressionfor tail probability needs to be known to understand which class a given probability distribution belongs to.It is usually not easy to get expressions for tail probabilities since most absolutely continuous probabilitydistributions are ...

Estimation of Tail Probabilities by Repeated Augmented Reality [PDF]

open access: yesJournal of Statistical Theory and Practice, 2021
Synthetic data, when properly used, can enhance patterns in real data and thus provide insights into different problems. Here, the estimation of tail probabilities of rare events from a moderately large number of observations is considered. The problem is approached by a large number of augmentations or fusions of the real data with computer-generated ...

Semiparametric Value-At-Risk Estimation of Portfolios. A replication study of Dias (Journal of Banking & Finance, 2014)

open access: yesInternational Journal for Re-Views in Empirical Economics, 2019
This paper aims to replicate the semiparametric Value-At-Risk model by Dias (2014) and to test its legitimacy. The study confirms the superiority of semiparametric estimation over classical methods such as mixture normal and Student-t approximations in ...
