generate.sample.h3: Two-levels hierarchical cluster generator.

Description

A 2-dimensional 2-levels hierarchical cluster structure is generated. At a first level 4 distinct clusters are generated. At a second level two other clusters at the left and right of 2 of the 4 "primary" clusters are generated (6 clusters)

Usage

generate.sample.h3(n = 20, DeltaA = 1, DeltaB = 1, seed = 0)

Value

a matrix with dim rows (variables) and n*6 columns (examples)

Arguments

n

number of examples for each cluster

DeltaA

vertical displacement of the the secondary clusters

DeltaB

horizontal displacement of the the secondary clusters

seed

seed for the random generator

Examples

generate.sample.h3()
# Generation of a data set with 120 2-dimensional examples
# data have a two-level hierarchical structure with respectively 4 and 6 clusters.
