\title{ Recursive Least Squares }
\description{
This function fits a linear model by recursive least squares.  It is
a utility routine for the \code{\link{khmaladzize}} function of the quantile regression
package.
}
\usage{
lm.fit.recursive(X, y, int=TRUE)
}
\arguments{
  \item{X}{ Design Matrix }
  \item{y}{ Response Variable}
  \item{int}{ if TRUE then append intercept to X}
}
\value{
return p by n matrix of fitted parameters, where p. The
ith column gives the solution up to "time" i.
