MST: Minimum Spanning Tree (MST)

In DataSimilarity: Quantifying Similarity of Datasets and Multivariate Two- And k-Sample Testing

Minimum Spanning Tree (MST)

Description

Calculte the edge matrix of a minimum spanning tree based on a distance matrix, used as helper functions in CCS, CF, FR, and ZC. This function is a wrapper around mstree. MST5 is a convinience wrapper for the 5-MST.

Usage

MST(dists, K = 1)
MST5(dists)

Arguments

dists	Distance matrix as dist object.
K	Component number (default: K = 1).

Details

For more details see mstree.

Value

Object of class neig.

Examples

set.seed(1234)
X1 <- matrix(rnorm(20), ncol = 2)
X2 <- matrix(rnorm(20, mean = 0.5), ncol = 2)
dists <- stats::dist(rbind(X1, X2))
if(requireNamespace("ade4", quietly = TRUE)) {
  # MST
  MST(dists)
  # 5-MST
  MST5(dists) 
}
