\title{Gibbs sampling for a robust regression model}
\description{
Implements Gibbs sampling for a robust t sampling model with location mu, scale sigma, and degrees of freedom v }
\usage{
robustt(y,v,m)
}
\arguments{
\item{y}{vector of data values}
\item{v}{degrees of freedom for t model}
\item{m}{the number of cycles of the Gibbs sampler}
}
\value{
\item{mu}{vector of simulated values of mu}
\item{s2}{vector of simulated values of sigma2}
\item{lam}{matrix of simulated draws of lambda, where each row corresponds to a single draw}
}
