Computes global variance

Global variance computation for a set of locations using the covarianve model

Keywords
spatial
Usage
globalvar(geodata, locations, coords = geodata$coords, krige)
Arguments
geodata

an object of the class geodata

locations

n by 2 matrix with a set of locations, typically a prediction grid

coords

data coordinates

krige

a list defining the model components and the type of kriging. It can take an output to a call to krige.control or a list with elements as for the arguments in krige.control.

Value

An scalar with the value of the global variance
