\title{Bayes factor against independence using uniform priors}
\description{
Computes a Bayes factor against independence for a two-way contingency table assuming
uniform prior distributions}

}
\arguments{
\item{y}{matrix of counts}
\item{a}{matrix of prior hyperparameters}
}
\value{
value of the Bayes factor against independence
}
