- Implementation of Class A as state space model:
- define variables
- z ≡ x, v ≡ i, w ≡ (c, t, d)'

- define G and H
- implementation trivial

- define variables
- Implementation of Class B as probabilistic state space
model:
- add two-dimensional random vector ξ = (ξ
_{R}, ξ_{D}) - define G, H and ξ
- implementation uses Binomial block from above

- add two-dimensional random vector ξ = (ξ
