\title{
Bias Test for Least-Squares Regression Estimates
}
\description{
Test for bias between least-squares and robust MM linear regression estimates.
}
\usage{
lsRobTest(object, test = c("T2", "T1"), ...)
}
\arguments{
\item{object}{an \code{lmRob} object (the output of the \code{\link{lmRob}} function).}
\item{test}{either \code{"T1"} or \code{"T2"}. Selects the null hypothesis. T2 (the default ): the error distribution not bias inducing. T1: the residual error distribution is normal.}
\item{\dots}{additional arguments are ignored.}
}
\examples{
rob.fit <- lmRob(stack.loss ~ ., data = stackloss)
lsRobTest(rob.fit)
lsRobTest(rob.fit, test = "T1")
