                  VAR:     X[t] = B1 X[t-1] + B2 X[t-2] + ... + v[t]
                           (Theory:  Bj = M* B(j-1))

                  VARMA:   X[t] = A X[t-1] + v[t] - B v[t-1]
                           (Theory:
                             A  = B1+M
                             B  = M )

                  SS:    S[t+1] = A S[t] + B eps[t+1]
                           X[t] = C S[t],   with A,B,C minimally restricted

      Section 4. Sensitivity with misspecification in model assumptions
                 (a) Economy has geometric growth, assumed unit root
                 (b) Economy has correlated shocks, assumed uncorrelated
                 (c) Economy has N shocks, assumed < N
