based on the <code>laplace</code> (approximation) method are <em>smoothed</em> estimates, meaning that all states are optimized jointly, given all observations in the data. The Laplace Approximation is natively built-into and completely handled by <strong>TMB</strong>. The package implements the stability-improved method due to <a href="https://arxiv.org/abs/2503.21358" class="external-link">Thygesen, 2025</a>.</p>
