ctmcmove (version 1.2.10)

Modeling Animal Movement with Continuous-Time Discrete-Space Markov Chains

Description

Software to facilitates taking movement data in xyt format and pairing it with raster covariates within a continuous time Markov chain (CTMC) framework. As described in Hanks et al. (2015) , this allows flexible modeling of movement in response to covariates (or covariate gradients) with model fitting possible within a Poisson GLM framework.
