chiSq_dis: Chi-square distance matrice between points

In yingtliu/distPack: Evaluate distance matrice based on points in coordinates by different methods

Description

Computes the Chi-square distance between n points in m dimensions ,or two points with same dimensions.

Usage

chiSq_dis(x, y, output = "matrix")

Arguments

x	Numeric vector, or a matrix with size n x m.
y	(optional)Numeric vector; must be the same length as x. If no input of y, please specify all other parameters to avoid confusion.
output	Format of output, either matrix or dist object. Default is matrix.

Value

Chi-square distance matrix or object calculated by sum((x - y)^2 /(x + y)) between points

Examples

chiSq_dis(x = matrix(c(1, 2, 3, 4), 2, 2), output = "dist")

chiSq_dis(rnorm(10), rnorm(10))
