maxgrid: Identifies the coordinates of the maximum on a grid
In HiDimMaxStable: Inference on High Dimensional Max-Stable Distributions

Description Usage Arguments Value See Also Examples

Finds the maximum likelihood point from a maxgrid object.

1	maxgrid(dg)

`dg`	an object returned by a `dens.grid` call.

returns a list l including parameters used in the dens.grid call of l$params, the coordinates of the maximum on the grid l$xy, and the value of the maximum l$value.

plot3d.densgrid for a 3D visualisation of the computed values on the grid.
