\title{Logarithm of integral of Bayes factor for testing homogeneity of proportions}
\description{
Computes the logarithm of the integral of the Bayes factor for testing homogeneity of a set of proportions
}
\usage{
bfexch(theta,datapar)
}
\arguments{
\item{theta}{value of the logit of the prior mean hyperparameter}
\item{datapar}{list with components data, matrix with columns y (counts) and n (sample sizes), and K, prior
precision hyperparameter}
}
\value{
value of the logarithm of the integral
}
