stats.SimilarityOfVectors: Similarity between vectors

In dimitrisk/goal: GeOgraphical Analysis Library

Similarity between vectors

Description

A weighted similarity measure between two numeric vectors.

Usage

stats.SimilarityOfVectors(weights, final, initial)

Arguments

weights	Vector of weights for each observation.
final	Vector of numbers.
initial	Vector of numbers.

Value

A percentage of similarity between the two numeric vectors.

Examples

library(goal)

weights=c(0.5, 0.25, 0.25)
final=c(42,5,36)
initial=c(40,5,36)

plot(final, initial, cex=weights*2, col="red",
  xlim=range(initial, final), ylim=range(initial, final))
abline(0,1)

per = goal::stats.SimilarityOfVectors(weights, final, initial)
print(per)
