\title{Function to choose method for Weighted Quantile Regression }
\description{ Weight the data and then call the chosen fitting algorithm. }
\usage{
rq.wfit(x, y, tau=0.5, weights, method="br", ...)
}
\arguments{
\item{x}{
the design matrix
}
\item{y}{
the response variable
}
\item{tau}{
the quantile desired, if tau lies outside (0,1) the whole process
is estimated.
}
\item{weights}{
weights used in the fitting
}
\item{method}{
method of computation: "br" is Barrodale and Roberts exterior point
"fn" is the Frisch-Newton interior point method.
}
\item{...}{
Optional arguments passed to fitting routine.
}
