clust2params {qcluster}R Documentation

Converts Hard Assignment Into Cluster Parameters

Description

Transforms cluster labels into a list of parameters describing cluster size, mean, and dispersion.

Usage

   clust2params(data, cluster)

Arguments

data

a numeric vector, matrix, or data frame of observations. Rows correspond to observations and columns correspond to variables/features. Categorical variables and NA values are not allowed.

cluster

a vector of integers representing cluster labels.

Value

A list containing cluster parameters. Let P=number of variable/features and K=number of clusters. The elements of the list are as follows:

Examples

# load data
data("banknote")

# compute the k-means partition 
set.seed(2024)
cl <- kmeans(banknote[-1], centers = 2, nstart = 1)$cluster

# convert k-means hard assignment into cluster parameters 
clpars <- clust2params(banknote[-1], cl) 
clpars
