e posterior deviations in a Kalman filter. This allows developers to write plug-ins for new calculations, without needing to alter “kalmanFilter.run”. The use of these calculators allows users to calculate values using the posterior, without needing to save the (often very large) posterior as output.</p>
<p>Subclasses implement the actual calculations, and implement methods that allow “kalmanFilter.run” to preallocate their output.</p>
