Copula Modelling of Serially Correlated Multivariate Data with Hidden Structures
Robert Zimmerman, Radu V. Craiu, Vianey Leos-Barajas
We propose a copula-based extension of the hidden Markov model (HMM) which applies when the observations recorded at each time in the sample are multivariate. The joint model produ…
Approximate Bayesian inference for a "steps and turns" continuous-time random walk observed at regular time intervals
Sofia Ruiz-Suarez, Vianey Leos-Barajas, Ignacio Alvarez-Castro +1
The study of animal movement is challenging because it is a process modulated by many factors acting at different spatial and temporal scales. Several models have been proposed whi…
Multi-scale modeling of animal movement and general behavior data using hidden Markov models with hierarchical structures
Vianey Leos-Barajas, Eric Gangloff, Timo Adam +4
Hidden Markov models (HMMs) are commonly used to model animal movement data and infer aspects of animal behavior. An HMM assumes that each data point from a time series of observat…
