minkowski: Minkowski distance

Description

The Minkowski metric is a generalized form of Euclidean (p=2) and Manhattan (p=1) distance.

Usage

minkowski(x, y, p = 1)

Arguments

x, y

Numeric vectors.

p

Exponent parameter, a single number greater than zero.

Value

The Minkowski distance between x and y.

Details

For vectors x and y, the Minkowski distance is defined as $$d(x, y) = \left( \sum_i |x_i - y_i|^p \right)^{1/p}.$$ Relation to other definitions:

  • Equivalent to R's built-in dist() function with method = "minkowski".

  • Equivalent to the minkowski() function in scipy.spatial.distance.

  • Equivalent to \(D_6\) in Legendre & Legendre.

The default value of p = 1 makes this distance equal to the Manhattan distance.
