A novel two-parameter discrete exponentiated exponential distribution with its neutrosophic extension: mathematical characterization and real-world count data modeling [PDF]

Frontiers in Big Data
This paper proposes and studies the Discrete Exponentiated Exponential (DEE) distribution, a new two-parameter discrete lifetime model obtained by applying the survival discretization technique to the exponentiated exponential distribution.

Reliability evaluation of PV modules based on exponential dispersion process

Energy Reports, 2021
The performance of photovoltaic (PV) modules gradually declines as the operational time continues due to the impacts of workload and environmental factors. This performance degradation process is dynamic and random.

On Some Layer-Based Risk Measures with Applications to Exponential Dispersion Models [PDF]

Journal of Probability and Statistics, 2010
Layer-based counterparts of a number of well-known risk measures have been proposed and studied. Namely, some motivations and elementary properties have been discussed, and the analytic tractability has been demonstrated by developing closed-form ...

Exponential Dispersion Models

Journal of the Royal Statistical Society Series B: Statistical Methodology, 1987
SUMMARY We study general properties of the class of exponential dispersion models, which is the multivariate generalization of the error distribution of Nelder and Wedderburn’s (1972) generalized linear models. Since any given moment generating function generates an exponential dispersion model, there exists a multitude of exponential ...

Linear stability and dispersive soliton propagation in nonlinear media subject to parabolic phase modulation [PDF]

Scientific Reports
This work investigates dispersive optical solitons governed by a perturbed cubic–quartic nonlinear Schrödinger equation with parabolic self-phase modulation, a model of direct relevance to high-capacity fiber-optic systems where simultaneous higher-order

Exponential dispersion models for overdispersed zero-inflated count data [PDF]

Communications in Statistics - Simulation and Computation, 2021
We consider three new classes of exponential dispersion models of discrete probability distributions which are defined by specifying their variance functions in their mean value parameterization. In a previous paper (Bar-Lev and Ridder, 2020a), we have developed the framework of these classes and proved that they have some desirable properties. Each of

Effects of Physical Properties and Environmental Conditions on the Natural Dispersion of Oil

Journal of Marine Science and Engineering, 2023
The natural dispersion of oil depends on the oil types, wave-mixing energy, and the temperature and salinity of water. Laboratory experiments were conducted to investigate the effects of these factors on oil dispersion.

A Review of CO₂ Plume Dispersion Modeling for Application to Offshore Carbon Capture and Storage

Journal of Marine Science and Engineering, 2023
The exponential increase in greenhouse gas emissions necessitates urgent measures to mitigate climate change impacts. Carbon capture and storage (CCS) has emerged as a promising solution, capturing CO2 from industrial processes and storing it underground.

Tail Conditional Expectations for Exponential Dispersion Models [PDF]

ASTIN Bulletin, 2005
There is a growing interest in the use of the tail conditional expectation as a measure of risk. For an institution faced with a random loss, the tail conditional expectation represents the conditional average amount of loss that can be incurred in a fixed period, given that the loss exceeds a specified value.
