exAM: Example Data of Antille and May - for Simple Regression

Description Usage Format Details Source Examples

Description

This is an artificial data set, cleverly construced and used by Antille and May to demonstrate ‘problems’ with LMS and LTS.

Usage

1

Format

A data frame with 12 observations on 2 variables, x and y.

Details

Because the points are not in general position, both LMS and LTS typically fail; however, e.g., rlm(*, method="MM") “works”.
