+\title{Estimate Impulse Response Coefficients}
+\usage{
+impulseest(x, M = 30, K = NULL, regul = F, lambda = 1)
+}
+\arguments{
+\item{x}{an object of class \code{idframe}}
+
+\item{M}{Order of the FIR Model (Default:\code{30})}
+
+\item{K}{Transport delay in the estimated impulse response 
+(Default:NULL)}
+
+\item{regul}{Parameter indicating whether regularization should be 
+used. (Default:\code{FALSE})}
+
+\item{lambda}{The value of the regularization parameter. Valid only if
+\code{regul=TRUE}. (Default:\code{1})}
+}
+\description{
+\code{impulseest} is used to estimate impulse response coefficients from 
+the data
+}
+\details{
+The IR Coefficients are estimated using linear least squares. Future 
+Versions will provide support for multivariate data.
+}
+\examples{
+uk <- rnorm(1000,1)
+yk <- filter (uk,c(0.9,-0.4),method="recursive") + rnorm(1000,1)
+data <- idframe(output=data.frame(yk),input=data.frame(uk))
