\title{Two-stage boundary operating characteristics}
\alias{oc.twostage.bdry}
\keyword{design}
\description{
Calculates the operating characteristics of a two-stage boundary.
}
\usage{
oc.twostage.bdry(pu, pa, r1, n1, r, n)
}
\arguments{
\item{pu}{unacceptable response rate}
\item{pa}{response rate that is desirable}
\item{r1}{first stage threshold to declare treatment undesirable}
\item{n1}{first stage sample size}
\item{r}{overall threshold to declare treatment undesirable}
\item{n}{total sample size}
}
\value{
oc.twostage.bdry returns the type I and II error rates as well as the
probability of early temination and expected sample size under pu for
a specific boundary.
