Software - DCRW and DCRWS state-space models

Posted in

This code supports state-space modelling of animal movement data using two models: DCRW (first-difference correlated random walk) and DCRWS (first-difference correlated random walk with switching). These models accomodate complex error structure in tracking data and allow fitting of behavioral models.
