Software - ctmm: Continuous-Time Movement Modeling

Posted in

The R package ctmm provides functions for identifying, fitting, and applying continuous-space, continuous-time stochastic movement models to animal tracking data. The package implements all major continuous-time models that have been applied to animal movement. In comparison to discrete-time and correlated-random-walk models, continuous-time models are insensitive to sampling schedule and can account for a wider range of autocorrelation structures. Fitted models can be leveraged to estimate home range, interpolate missing data, filter/smooth errors, etc.

It is developed by Chris H. Fleming and J. M. Calabrese at the Smithsonian Institute.

Compatibility with Movebank: 

The package uses the Movebank format for importing data into the package and uses the move package to allow download of data directly from Movebank.
