Application of the Heavy-tailed Estimation in Financial Data

open access: yesJournal of Harbin University of Science and Technology, 2019
There exist many marginal distributions of high frequency time series data in the Heavy-tailed distribution which stores a great deal of information in its tail.

Model Selection Test for the Heavy-Tailed Distributions under Censored Samples with Application in Financial Data

open access: yesInternational Journal of Financial Studies, 2016
Numerous heavy-tailed distributions are used for modeling financial data and in problems related to the modeling of economics processes. These distributions have higher peaks and heavier tails than normal distributions.

Generalized Skew Laplace Random Fields: Bayesian Spatial Prediction for Skew and Heavy Tailed Data

open access: yesJournal of Statistical Theory and Applications (JSTA), 2021
Earlier works on spatial prediction issue often assume that the spatial data are realization of Gaussian random field. However, this assumption is not applicable to the skewed and kurtosis distributed data.

ℓ1 Major Component Detection and Analysis (ℓ1 MCDA) in Three and Higher Dimensional Spaces

open access: yesAlgorithms, 2014
Based on the recent development of two dimensional ℓ1 major component detection and analysis (ℓ1 MCDA), we develop a scalable ℓ1 MCDA in the n-dimensional space to identify the major directions of star-shaped heavy-tailed statistical distributions with ...

Bayesian Adjustment for Insurance Misrepresentation in Heavy-Tailed Loss Regression

open access: yesRisks, 2018
In this paper, we study the problem of misrepresentation under heavy-tailed regression models with the presence of both misrepresented and correctly-measured risk factors.

The Arcsine Exponentiated-X Family: Validation and Insurance Application

open access: yesComplexity, 2020
In this paper, we propose a family of heavy tailed distributions, by incorporating a trigonometric function called the arcsine exponentiated-X family of distributions.

Modeling Heavy-Tailed Bounded Data by the Trapezoidal Beta Distribution with Applications

open access: yesRevstat Statistical Journal, 2022
In this paper, by using a new method, we derive the trapezoidal beta (TB) distribution and its properties. The TB distribution is a mixture model, generalizes both the beta and rectangular beta distributions, and allows one to describe bounded data with

Fitting Heavy Tailed Distributions: The poweRlaw Package

open access: yesJournal of Statistical Software, 2015
Over the last few years, the power law distribution has been used as the data generating mechanism in many disparate fields. However, at times the techniques used to fit the power law distribution have been inappropriate.

A Heavy-Tailed QLindley Distribution for Modelling Skewed Lifetime Data

open access: yesMathematics
Lifetime data arising in engineering reliability, survival analysis, actuarial science, and environmental studies often exhibit substantial right-skewness, extreme observations, and heterogeneous hazard-rate structures.
