Some Stochastic Orders over an Interval with Applications

L Kanellopoulos - Risks, 2023 - mdpi.com
In this article, we study stochastic orders over an interval. Mainly, we focus on orders related
to the Laplace transform. The results are then applied to obtain a bound for heavy-tailed …

Constructing an accurate model for insurance losses is a challenging task. Researchers
have developed various methods to model insurance losses, such as composite models …

New discrete heavy tailed distributions as models for insurance data

S Nadarajah, J Lyu - Plos one, 2023 - journals.plos.org
Although many data sets are discrete and heavy tailed (for example, number of claims and
claim amounts if recorded as rounded values), not many discrete heavy tailed distributions …

Alpha Power Exponentiated Pareto Distribution

P Pimsap, W Bodhisuwan, A Volodin - Lobachevskii Journal of …, 2023 - Springer
In this paper, we have proposed alpha power exponentiated Pareto distribution for lifetime
data to introduce a new class of alpha power transformation family. The statistical properties …
