= Prior density
{title2=$\pi(\theta)$}

A <prior density> is the <probability density function> of a continuous <prior distribution> with respect to a specified reference measure. A proper prior density is nonnegative and integrates to one. Prior-density factors enter <Bayesian posterior> and <RJ-MCMC> acceptance formulas along with the likelihood and model prior probabilities.
