Hi, would appreciate some help. Is there any command in Maple that would hep check general SARIMA equations? for instance, if we take the following model (0,1,0)*(1,1,1)_5, then the general SARIMA equation will be: (1 - K)*(1-K^5)*X_t = (1 + B*K)*(1+B*(K^5))*Z_t i.e. X_t - X_(t-1) - X_(t-5) + X_(t-6) = Z_t + B*Z_(t-1) + B*Z_(t-5)+ B*Z_(t-6) Is there any option in Maple that would allow me to check if this equation is correct? many thanx.
