A new family of heavy tailed distributions with an application to the heavy tailed insurance loss data

Communications in Statistics - Simulation and Computation, 2020
Heavy tailed distributions play very significant role in the study of actuarial and financial risk management data but the probability distributions proposed to model such data are scanty.

Anytime Guarantees under Heavy-Tailed Data

Proceedings of the AAAI Conference on Artificial Intelligence, 2022
Under data distributions which may be heavy-tailed, many stochastic gradient-based learning algorithms are driven by feedback queried at points with almost no performance guarantees on their own. Here we explore a modified "anytime online-to-batch" mechanism which for smooth objectives admits high-probability error bounds while requiring only lower ...

Models for Heavy Tailed Data and Applications

AIP Conference Proceedings, 2008
An important topic in space research is represented by the study of statistical properties of the interplanetary magnetic field fluctuations, these being closely related to acceleration processes and energy transport in the solar wind. Analysis of the probability distribution functions of the velocity and magnetic field fluctuations has underlined ...
