<p>For example, if <code>z</code> is data, this can be used to estimate <code>mu</code> and the covariance Cholesky factor <code>L_Sigma</code>. Alternatively, if <code>z</code> is a parameter, <code>mu</code> and <code>L_Sigma</code> may constants defining a prior or further parameters defining a hierarchical model.</p>
