emulate.ctmm.Rd
This function generates random modelfit statistics from the sampling distribution of a given ctmm
movement model and sampling schedule.
If fast=FALSE
, the results are exact, though slow to evaluate.
Else if fast=TRUE
, the centrallimit theorem is invoked.

CTMM  A

fast  Whether or not to invoke the centrallimit theorem. 
...  Arguments passed to 
Given fast=FALSE
, which requires the data
argument specified, new data are simulated from the CTMM
movement model with the same sampling schedule and error structure as data
. A new model, of the same structure as CTMM
, is then fit to the simulated data and returned.
Given fast=TRUE
, a modelfit object is sampled from the centrallimit distribution, using the covariance estimates within CTMM
.
Strictly positive parametes, such as area, are logtransformed prior to the normal approximation.
Note that this faster method does not adjust for bias.

movement model with the same structure as CTMM
