Description

Calculation of dispersion variance between two scales. This only works if a variogram model is available for the small scale. The dispersion variance quantifies how much of the total variance of a variable at small scale is happening inside the units of a larger units. You can also see it as the proportion of variance being lost when upscaling from the small to the large scale. The variance at large scale is the variance at small scale minus the dispersion variance between the two scales.

Usage

1
dispvar(vgm, small.scale = 100, large.scale = 1000)

Arguments

vgm

Variogram model (gstat) of a variable at small scale support

small.scale

Side length of an area unit of the smaller scale

large.scale

Side length of an area unit of the larger scale

Value

Dispersion variance
