ctmc.sim

Simulates a CTMC with given rate matrix (Q) for a time (T), or until
 it reaches a final absorbing state.

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.

<dl> <dt>Q</dt>
<dd>A square matrix. Either a rate matrix or the infinitessimal generator of the CTMC.</dd> <dt>start.state</dt>
<dd>An integer - the starting state for the simulation.</dd> <dt>T</dt>
<dd>A numeric value greater than zero. The time window for simulating the
CTMC will be [0,T].</dd> <dt>final.state</dt>
<dd>Either NA or an integer. If an integer, the chain will be simulated
 until it enters the "final.state", at which time the simulation will
 be terminated.</dd></dl>
