Analytical Derivatives for Markov Switching Models [PDF]

open access: yesComputational Economics, 1997
Dans cette étude, les auteurs dérivent des gradients analytiques pour toute une catégorie de modèles à changement de régime comportant des probabilités de transition à la Markov. Ces modèles sont généralement estimés à l'aide de méthodes du maximum de vraisemblance, qui nécessitent que la fonction de vraisemblance soit dérivée par rapport au vecteur ...

Evaluation of fall‐seeded cover crops for grassland nesting waterfowl in eastern South Dakota

open access: yesWildlife Society Bulletin, EarlyView., 2023
Cover crops are experiencing a revival among Midwestern farmers, and we assessed their attractiveness and safety for nesting ducks in South Dakota. Nest success was markedly lower in cover crops than in perennial cover during both years of our study, including 2019 which was a best‐case scenario for cover crops, with extremely wet conditions delaying ...

Using Markov switching models to infer dry and rainy periods from telecommunication microwave link signals [PDF]

open access: yesAtmospheric Measurement Techniques, 2012
A Markov switching algorithm is introduced to classify attenuation measurements from telecommunication microwave links into dry and rainy periods. It is based on a simple state-space model and has the advantage of not relying on empirically estimated ...

Markov Switching Vector Autoregressive Modelling of the Nigerian Stock Price and Oil Price Series

open access: yesQuantitative Economics Research, 2018
This article studied the relationship between stock prices and crude oil prices of Nigeria using a Markov switching model. Certain properties of the stock price series and crude oil price series such as breaks and stationarity, which are necessary before

Control problem for the impulse process under stochastic optimization procedure and Levy conditions

open access: yesМатематичні Студії, 2021
A stochastic approximation procedure and a limit generator of the original problem are constructed for a system of stochastic differential equations with Markov switching and impulse perturbation under Levy approximation conditions with control, which is

Semi-Markov Switching Vector Autoregressive Model-Based Anomaly Detection in Aviation Systems [PDF]

open access: yesJournal of Aerospace Information Systems, 2016
In this work we consider the problem of anomaly detection in heterogeneous, multivariate, variable-length time series datasets. Our focus is on the aviation safety domain, where data objects are flights and time series are sensor readings and pilot ...

Identifying Physical Interactions in Contact‐Based Robot Manipulation for Learning from Demonstration

open access: yesAdvanced Robotics Research, EarlyView.
Robots can learn manipulation tasks from human demonstrations. This work proposes a versatile method to identify the physical interactions that occur in a demonstration, such as sequences of different contacts and interactions with mechanical constraints.
