State dynamics are therefore given by (30.5) with A = 1, Q = 0 and x 0 = θ. The measurement equation is y t = θ + v t where v t is N ( 0, 1) and IID. The task of this exercise to simulate the model and, using the code from **kalman**.py, plot the first five predictive densities p t ( x) = N ( x ^ t, Σ t).

Once the **Kalman filter** has been applied to the entire time range, you have optimal estimates of the states a t, P t for t = 1, 2, , T. Imputing data is then **simple** via the measurement equation. In particular, you just calculate: y ^ t = Z a t. As for a reference, Durbin and Koopman (2012) is excellent; section 4.10 discusses missing.
