%% Modify Model Properties % You can also modify model properties using dot notation. For example, % consider this AR(2) specification: %% % Copyright 2015 The MathWorks, Inc. Mdl = arima('AR',{0.8,-0.2},'Variance',0.2,'Constant',0) %% % The created model has the default Gaussian innovation distribution. % Change the innovation distribution to a Student's _t_ distribution with % eight degrees of freedom. The data type for |Distribution| is a |struct| % array. Mdl.Distribution = struct('Name','t','DoF',8) %% % The variable |Mdl| is updated accordingly.
