Ichino-Yaguchi dissimilarity for intervals

Computes the Ichino-Yaguchi dissimilarity between interval-valued observations based on intersection and union of intervals.

Usage

idist_ichino_yaguchi(centers, radii, gamma = 0.5)

Arguments

centers

Numeric matrix of interval midpoints (n x p).

radii

Numeric matrix of interval half-widths (n x p).

gamma

Weighting parameter (default 0.5).

Value

A symmetric n x n distance matrix.

Examples

C <- matrix(rnorm(12), 4, 3)
R <- matrix(runif(12, 0.1, 0.5), 4, 3)
D <- idist_ichino_yaguchi(C, R)
