<h3>Generating Transitions</h3>
<p>Starting from the current value of the parameters <span class="math inline">\(\theta\)</span>, a
transition to a new state is generated in two stages before being
subjected to a Metropolis accept step.</p>
<p>First, a value for the momentum is drawn independently of the current
parameter values,</p>

\rho \sim \mathsf{MultiNormal}(0, \Sigma).
\]</span></p>
<p>Thus momentum does not pers
