<h3>Includes Jacobian</h3>
<p>The log density includes the Jacobian adjustment implied by the
constraints declared on variables. The Jacobian adjustment for
constrained parameter transforms will be turned off if optimization is
used in practice, but there is as of yet no way to turn it off in
diagnostic mode.</p>
