Hidden Markov Models and Animal Behaviour
Iain L. MacDonald, David Raubenheimer · Biometrical Journal · 1995
Abstract This paper proposes the use of hidden Markov time series models for the analysis of the behaviour sequences of one or more animals under observation. These models have advantages over the Markov chain models commonly used for behaviour sequences, as they can allow for time‐trend or expansion to several subjects without sacrificing parsimony. Furthermore, they provide an alternative to higher‐order Markov chain models if a first‐order Markov chain is unsatisfactory as a model. To illustrate the use of such models, we fit multivariate and univariate hidden Markov models allowing for time‐trend to data from an experiment investigating the effects of feeding on the locomotory behaviour of locusts (Locusta migratoria).
