\title{
normal discretization normalization
}
\description{
Performs a discretization of continous expression levels to discrete steps.
}
\usage{
normalize.ExpressionSet.nordi(ExpressionSet = NULL, pvalue = 0.01, alpha = 0.05)
}
\arguments{
  \item{ExpressionSet}{
An ExpressionSet object
}
  \item{pvalue}{
The pvalue determines the sensitivity for detecting outliers in each column of the gene expression matrix.
}
  \item{alpha}{
The alpha value determines the size of the tails of the normal distributions considered to be over or under expressed.
}
}
\details{

\value{
An ExpressionSet object with adjusted expression matrix.
