s to be specified with multiple parameters, datasets and allows separate tuning constants to be set for each parameter. We assume that observations are always accessed on the first dimension of each object, i.e. the point <span class="math inline">\(x_i\)</span> is located at <code>X[i,]</code> rather than <code>X[,i]</code>. Similarly the observation <span class="math inline">\(i\)</span> from a 3d object <code>Y</code> would be located at <code>Y[i,,]</code>.</p>
