%% Create SARIMA Model Template
% Create the SARIMA\left(0,1,1\right)\times {\left(0,1,1\right)}_{12} model (multiplicative, monthly MA model template with one degree of seasonal and nonseasonal integration) represented by this equation:
% (1 - L)(1 - {L^{12}}){y_t} = (1 + {\theta _1}L)(1 + {\theta _{12}}{L^{12}}){\varepsilon _t},
% where \varepsilon_t is a series of iid Gaussian random variables with mean 0 and variance \sigma^2.

Mdl = arima('Constant',0,'D',1,'Seasonality',12,...
	'MALags',1,'SMALags',12)
