%% Create Default Model
% Create a default ARIMA model by using arima.

Mdl = arima

% Mdl is an arima object. Properties of the model appear at the command line.
% The default model is
% y_t=c+\varepsilon_t,
% where c is an unknown constant and \varepsilon_t \; is a series of iid Gaussian random variables with mean 0 and variance \sigma^2.
% Mdl is a model template for estimation. You can modify property values by using dot notation or fit the model to data by using estimate, but you cannot pass Mdl to any other object function.
