\title{
mean integrated squared error for density estimation with normal data
}
\description{
This function evaluates the mean integrated squared error of a density
estimate which is constructed from data which follow a normal distribution.
}
\usage{
nmise(sd, n, h)
}
\arguments{
\item{sd}{
the standard deviation of the normal distribution from which the data arise.
}
\item{n}{
the sample size of the data.
}
\item{h}{
the smoothing parameter used to construct the density estimate.
}}
\value{
the mean integrated squared error of the density estimate.
}
\details{
see Section 2.4 of the reference below.
