\title{Log posterior of a Bradley Terry random effects model}
\description{
Computes the log posterior density of the talent parameters and the log
standard deviation for a Bradley Terry model with normal
random effects
}
\usage{
bradley.terry.post(theta,data)
}
\arguments{
\item{theta}{vector of talent parameters and log standard deviation}
\item{data}{data matrix with columns team1, team2, wins by team1, and
wins by team2}
}
\value{value of the log posterior}
