surrogateCrawlModel: Crawl Movement Model
In AustralianAntarcticDataCentre/availability: Estimating Geographic Space Available to Animals Based on Telemetry Data
surrogateCrawlModel R Documentation
Crawl Movement Model
Description
Generate Transition and Covariance Matrices for a simple Crawl Model
Usage
surrogateCrawlModel(fit, dt)
Arguments
fit
a fitted crawl object
dt
the fixed time increment
Details
Generates the transition and covariance matrices of the state
space model for time increment dt, corresponding to a
fitted crawl model with no drift and no covariates.
Currently no polar adjustment is made.
The matrices are generated assuming the state variables are stored
as a vector in the order longitude mu and nu then latitude mu and
nu. The parametrization is defined as in the crawl source not the
paper, which differs by a factor of \beta^{2} in the
definition of \sigma^{2}.
Value
A list containing
A
the transition matrix
Q
the covariance matrix
dt
the time increment
