Statistical Modeling of Animal Movements

Animal movement models including moving-resting process with embedded Brownian motion according to Yan et al. (2014) , Pozdnyakov et al. (2017) , Brownian motion with measurement error according to Pozdnyakov et al. (2014) , and moving-resting-handling process with embedded Brownian motion, Pozdnyakov et al. (2018) .

CHANGES IN smam VERSION 0.4.0

MAJOR CHANGES

  • Added moving-resting-handling model with both full likelihood and composite likelihood.

  • Provided option to use only part of dataset to fit BMME model, moving-resting model and moving-resting-handling model (in function fitBMME, fitMR, and fitMRH).

  • Provided tools for seasonal behavior analysis.

  • Parallel code is implemented for moving-resting-handling model to speed code up.

  • Added code for predicting state at given time point under MR model and MRH model (beta version).

MINOR CHANGES

  • Added vignette for quick start.

  • Redocumented whole package.

  • Renamed rBmme -> rBMME, fitBmme -> fitBMME, rMovRes -> rMR and fitMovRes -> fitMR.

  • Provided option to show simulated states in rMR and rMRH.

CHANGES IN smam VERSION 0.3.0

MAJOR CHANGES

  • Added full likelihood based hidden Markov model

  • Full likelihood and composite likelihood are now done with Rcpp
