site_fidelity: Test for site fidelity of animal movement.
Description
Calculates two indices (mean squared displacement and linearity) to test for site fidelity. Significance testing is done by permuting step lengths and drawing turning angles from a uniform distribution.
Usage
site_fidelity(x, ...)
# S3 method for steps_xy
site_fidelity(x, n = 100, alpha = 0.05, ...)
Value
A list of length 4. msd_dat and li_dat is the mean square distance and linearity for the real date. msd_sim and `li_sim`` are the mean square distances and linearities for the simulated trajectories.
Arguments
x
A track
...
None implemented
n
Numeric scalar. The number of simulated trajectories.
alpha
Numeric scalar. The alpha value used for the bootstrapping.
