# household: Load 'household' data In T4cluster: Tools for Cluster Analysis

## Description

The data is taken from HSAUR3 package's household data. We use housing, service, and food variables and normalize them to be unit-norm so that each observation is projected onto the 2-dimensional sphere. The data consists of 20 males and 20 females and has been used for clustering on the unit hypersphere.

## Usage

 1 data(household) 

## Format

a named list containing

data

an (n\times 3) data matrix whose rows are unit-norm.

gender

a length-n factor for class label.
