Code to simulate a continuous-time Markov chain.
Convert a "ctmc" object into Poisson glm format.
ctmcmove
Create a CTMC rate matrix from rasters and parameter estimates.
Find the stationary distribution of the CTMC.
Fit continuous-time functional movement model to telemetry data.
Function to turn a discrete-time continuous-space path into a CTMC pat...
Transition Matrix of a CTMC.
Creates gradient rasters from a raster object.
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) <DOI:10.1214/14-AOAS803> , this allows flexible modeling of movement in response to covariates (or covariate gradients) with model fitting possible within a Poisson GLM framework.
