The hot hand in professional darts

JOURNAL OF THE ROYAL STATISTICAL SOCIETY SERIES A-STATISTICS IN SOCIETY, 183(2), 565–580.

By: M. Oetting, R. Langrock*, C. Deutscher* & V. Leos-Barajas n

author keywords: Hidden Markov model; Hot hand; Sports statistics; State space model; Time series
TL;DR: A strong but short-lived serial dependence is found in the latent state process, which provides evidence for the existence of the hot hand in professional darts. (via Semantic Scholar)

2020 journal article

Using approximate Bayesian inference for a "steps and turns'' continuous-time random walk observed at regular time intervals

PEERJ, 8.

author keywords: Movement Ecology; Approximate Bayesian Computation; Observation Time-Scale; Random walk; Simulated Trajectories; Animal Movement
TL;DR: The state-space model used here allowed us to connect the scales of the observations and movement decisions in an intuitive and easy to interpret way and underscore the idea that the time scale at which animal movement decisions are made needs to be considered when designing data collection protocols.

Joint modelling of multi‐scale animal movement data using hierarchical hidden Markov models

Methods in Ecology and Evolution, 10(9), 1536–1550.

Ed(s): M. Auger‐Méthé

author keywords: animal movement modelling; biologging; state-space models; statistical ecology; temporal resolution; time series modelling
TL;DR: H hierarchical hidden Markov models are proposed as a versatile statistical framework that naturally accounts for differing temporal resolutions across multiple variables, and can be used to infer behavioural modes at multiple time‐scales and help to draw a much more comprehensive picture of an animal's movement patterns.

State‐space modeling reveals habitat perception of a small terrestrial mammal in a fragmented landscape

Ecology and Evolution, 9(17), 9804–9814.

author keywords: conservation; fragmentation; Hidden Markov Models; management; movement ecology; restoration
TL;DR: This work demonstrates the value of using animal movement to understand how animals respond to variation in habitat structure, including fragmentation, and was able to characterize distinct habitat types needed for foraging and denning, and identify landscape features that facilitate movement between patches.

Activity seascapes highlight central place foraging strategies in marine predators that never stop swimming

Movement Ecology, 6(1).

author keywords: Sharks; Acceleration; Hidden Markov models; Coral reefs; Foraging; Telemetry
TL;DR: It is shown that blacktip and grey reef sharks behave as CPFs, with diel changes in activity, horizontal and vertical space use, however, aspects of their foraging behavior may differ from other predictions of traditional CPF models. (via Semantic Scholar)

Optimal swimming strategies and behavioral plasticity of oceanic whitetip sharks

Scientific Reports, 8(1).

By: Y. Papastamatiou*, G. Iosilevskii*, V. Leos-Barajas*, E. Brooks*, L. Howey*, D. Chapman*, Y. Watanabe*

MeSH headings : Adaptation, Physiological; Animals; Energy Metabolism; Oceans and Seas; Predatory Behavior; Sharks / metabolism; Sharks / physiology; Swimming
TL;DR: Using biologging sensors, it is shown that oceanic whitetip shark behavior matches two canonical swimming strategies for pelagic predators, that maximize their energy surplus while foraging. (via Semantic Scholar)

Spline-based nonparametric inference in general state-switching models

Statistica Neerlandica, 72(3), 179–200.

By: R. Langrock*, T. Adam*, V. Leos-Barajas*, S. Mews*, D. Miller* & Y. Papastamatiou*

author keywords: hidden Markov model; maximum penalized likelihood; Markov-switching regression; penalized splines
TL;DR: An overview of ways to use penalized splines to allow for flexible nonparametric inference within state‐switching models, and a critical discussion of the use of corresponding classes of models are provided. (via Semantic Scholar)

Integrating behaviour into the pace-of-life continuum: Divergent levels of activity and information gathering in fast- and slow-living snakes

Behavioural Processes, 142, 156–163.

By: E. Gangloff*, M. Chow*, V. Leos-Barajas*, S. Hynes*, B. Hobbs* & A. Sparkman*

author keywords: Tongue flicks; Movement; Hidden Markov model; Predation; Habituation; Pace-of-life syndrome; Tharnnophis elegans
MeSH headings : Animals; Colubridae / physiology; Female; Habituation, Psychophysiologic; Life Style; Male; Markov Chains; Movement / physiology; Sex Factors; Tongue / physiology
TL;DR: Evidence is offered that behaviour is an important component of co-evolved suites of traits forming a general pace-of-life continuum in this system and environmental factors experienced by the fast-living ecotype select for both increased information-gathering and activity levels to facilitate efficient responses to repeated challenges.

Multi-scale Modeling of Animal Movement and General Behavior Data Using Hidden Markov Models with Hierarchical Structures

Journal of Agricultural, Biological and Environmental Statistics, 22(3), 232–248.

author keywords: Animal behavior; Bio-logging; Experimental design; Latent process; State-switching model; Temporal resolution
TL;DR: This work proposes a hierarchically structured HMM framework, one of the first that models animal behavior simultaneously at multiple time scales, opening new possibilities in the area of animal movement and behavior modeling. (via Semantic Scholar)

Analysis of animal accelerometer data using hidden Markov models

Methods in Ecology and Evolution, 8(2), 161–173.

Ed(s): R. O'Hara

author keywords: activity recognition; animal behaviour; latent states; serial correlation; time series
TL;DR: The ability to combine direct observations of animal activity with statistical models, which account for the features of accelerometer data, offers a new way to quantify animal behaviour and energetic expenditure and to deepen the insights into individual behaviour as a constituent of populations and ecosystems.

Sex-specific and individual preferences for hunting strategies in white sharks

Functional Ecology, 30(8), 1397–1407.

By: A. Towner*, V. Leos-Barajas*, R. Langrock*, R. Schick*, M. Smale*, T. Kaschke*, O. Jewell*, Y. Papastamatiou*

Ed(s): W. Hopkins

author keywords: acoustic telemetry; foraging mode; fine-scale movement; hidden Markov Model; predator-prey
TL;DR: White sharks demonstrate individual preferences for fine-scale movement patterns, which may be related to their use of different hunting modes, and it is shown that there may be a mix within populations. (via Semantic Scholar)
