Description Arguments Author(s) References Examples
This function creates a utilization distribution according to the Bivariate Gaussian Bridge model. It returns an object of the class dynBGB-class.
move |
the move object or variance object used for
calculating the ud if a |
raster |
either the raster used for UD calculation or the resolution of the raster used for UD calculation |
locErr |
the location errors used for the calculation |
