Several research papers have attempted to describe the dynamics of COVID-19 based on systems of differential equations. These systems have taken into account quarantined or isolated cases, vaccinations, control measures, and demographic parameters, p

Seismic temporal properties constitute a fundamental component in developing probabilistic models for earthquake occurrence in a specific area. Earthquake occurrence is neither periodic nor completely random but often accrues into bursts in both shor

The efficiency of earthquake clustering investigation is improved as we gain access to larger datasets due to the increase of earthquake detectability. We aim to demonstrate the robustness of a new clustering method, MAP-DBSCAN, and to present a comp

State space model representation is widely used for the estimation of nonobservable (hidden) random variables when noisy observations of the associated stochastic process are available. In case the state vector is subject to constraints, the standard

Observational errors of Particle Filtering are studied over the case of a state-space model with a linear observation equation. In this study, the observational errors are estimated prior to the upcoming observations. This action is added to the basi

In the first part of the paper, the positive and negative jumps of NASDAQ daily (log-) returns and three of its stocks are estimated based on the methodology presented by Theodosiadou et al. 2016, where jumps are assumed to be hidden random variables

Ce chapitre montre que l’évolution temporelle des groupes de séismes identifiés est cohérente avec celles obtenues par des études antérieures de séquences sismiques sélectionnées, et que les états cachés des taux de sismicité les plus

Méthodes et modèles statistiques pour la sismogenèse ISBN: 9781789480375
Ce chapitre constitue un examen détaillé de la détection des points de changement dans la modélisation de la sismicité, en combinant à la fois des modèles de points de changement fondamentaux et une étude récente dans ce domaine.
