Defines a distance metric for the AGS

Description

Defines a distance metric for the AGS

Usage

ags_dist(x, y, landw = 10^6, kreisw = 10^3, gemw = 1, ceiling = 99999999)

Arguments

x, y	vectors of AGS values
landw	weight of the Bundesland (Land) integers
kreisw	weight of the Kreis (district) integers
gemw	weight of the Gemeinde (municipality) integers
ceiling	truncate all distances at this value

Details

The distance metric is defined as

abs(x[1:2]- y[1:2])*landw + abs(x[3:5]- y[3:5])*kreisw + abs(x[6:8]- y[6:8])*gemw,

where z[a:b] means all digits between a and b for integer z.

With the default weights, this sum is the absolute difference between x and y.

Value

A numerical vector.

Examples

ags_dist(14053,14059)
