60:80 data

Description

An example with two clusters. The first 80 units form a rather diffuse group, while the remaining 60 units form a tight cluster.

Usage

data(sixtyeighty.dat)

Format

A data frame with 140 observations on the following 2 variables.

y1
a numeric vector.
y2
a numeric vector.

Details

When we fit a single model to these data, neither standard classical methods nor very robust methods yield Mahalanobis distances which unambiguously show that there are two different groups of observations.
