%% Create Nonseasonal ARIMA Model Template
% Create the ARIMA(3,1,2) model represented by this equation:
% (1 - {\phi _1}L - {\phi _2}{L^2} - {\phi _3}{L^3})(1 - L){y_t} = (1 + {\theta _1}L + {\theta _2}{L^2}){\varepsilon_t},
% where \varepsilon_t is a series of iid Gaussian random variables with mean 0 and variance \sigma^2.
% Because the model contains only nonseasonal polynomials, use the shorthand syntax.

Mdl = arima(3,1,2)

% The property P is equal to p + D = 4. NaN-valued elements indicate estimable parameters.
