 values drawn uniformly from the interval <span class="math inline">\((-2,2)\)</span>. The bounds of this initialization can be changed but it is always symmetric around 0. The value of 0 is special in that it represents the median of the initialization. An unconstrained value of 0 corresponds to different parameter values depending on the constraints declared on the parameters.</p>
<p>An unconstrained real does not involve any transform, so an initial value of 0 for the unconstrained parameters is also a v
