\title{Example Data of Antille and May - for Simple Regression}
\description{
This is an artificial data set, cleverly construced and used by
Antille and May to demonstrate \sQuote{problems} with LMS and LTS.
}
\usage{data(exAM)}
\format{
A data frame with 12 observations on 2 variables, \code{x} and \code{y}.
}
\details{
Because the points are not in general position, both LMS and LTS
typically \emph{fail}; however, e.g., \code{\link[MASS]{rlm}(*,
method="MM")} \dQuote{works}.
