<li><p><strong>Kalman filters:</strong> In this case the argument
controls the time-step used for the <em>euler</em> and <em>rk4</em> ODE
solvers.</p></li>

controls the number of added intermediate time-points between
observations each of which represents an additional state (random
effect) at that particular time-point.</p></li>
