Optimal mean-variance reinsurance and investment strategy with constraints in a non-Markovian regime-switching model

open access: yesStatistical Theory and Related Fields, 2020
This paper is devoted to study the proportional reinsurance/new business and investment problem under the mean-variance criterion in a continuous-time setting.

Volatility spillover in crude oil market using Heston switching Clayton model [PDF]

open access: yesMathematics and Modeling in Finance, 2023
The purpose of this study is to investigate the effects and risk spillover from the global crude oil market on Tehran Stock Exchange Oil Group. For this purpose, we used a combination of copula models and switching models in this research. First, we will

Adding flexibility to Markov Switching models [PDF]

open access: yesStatistical Modelling, 2016
Abstract: Very often time series are subject to abrupt changes in the level, which are generally represented by Markov Switching (MS) models, assuming that the level is constant within a certain state (regime). This is not a realistic framework because in the same regime the level could change with minor jumps with respect to a change of state; this ...

Event-Based Consensus Tracking for Nonlinear Multi-Agent Systems Under Semi-Markov Jump Topology

open access: yesIEEE Access, 2021
This paper studies the event-triggering leader-follower consensus with the strictly dissipative performance for nonlinear multi-agent systems (MASs) with semi-Markov changing topologies.

The Adaptive Market Hypothesis and the Day-of-the-Week Effect in African Stock Markets: the Markov Switching Model

open access: yesComparative Economic Research. Central and Eastern Europe, 2019
In line with the Adaptive Market Hypothesis (AMH), the objective of this study is to investigate how the day-of-the-week (DOW) effect behaves under different bull and bear market conditions in African stock markets, and to examine the likelihood of being

Explicit-Duration Markov Switching Models [PDF]

open access: yesFoundations and TrendsĀ® in Machine Learning, 2014
Markov switching models (MSMs) are probabilistic models that employ multiple sets of parameters to describe different dynamic regimes that a time series may exhibit at different periods of time. The switching mechanism between regimes is controlled by unobserved random variables that form a first-order Markov chain.

Markov-Switching Bayesian Vector Autoregression Model in Mortality Forecasting

open access: yesRisks, 2023
We apply a Markov-switching Bayesian vector autoregression (MSBVAR) model to mortality forecasting. MSBVAR has not previously been applied in this context, and our results show that it is a promising tool for mortality forecasting. Our model shows better

Uncertainty Through the Lenses of a Mixed-Frequency Bayesian Panel Markov Switching Model

open access: yesAnnals of Applied Statistics, 2017
We propose a Bayesian panel model for mixed frequency data whose parameters can change over time according to a Markov process. Our model allows for both structural instability and random effects.

A Markov-switching model for heat waves [PDF]

open access: yes, 2014
Heat waves merit careful study because they inict severe economic and societal damage. We use an intuitive, informal working denition of a heat wave|a persistent event in the tail of the temperature distribution| to motivate an interpretable latent state
