R: Computes global variance

globalvar {geoR} | R Documentation

## Computes global variance

### Description

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

### 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
