\description{
Calculates the Concordance Probability Estimate for a Cox model.
}
\usage{
coxphCPE(phfit)
}
\arguments{
\item{phfit}{output from a proportional hazards fit.}
}
\value{
coxphCPE returns a vector with CPE, smooth.CPE & se.CPE which are the
estimate, the smoothed estimate and its standard error respectively.
