    %% Create GARCH Model
% Create a |garch| model using name-value pair
% arguments.
%%
% Specify a GARCH(1,1) model. By default, the conditional mean model offset
% is zero.  Specify that the offset is |NaN|.

% Copyright 2015 The MathWorks, Inc.

Mdl = garch('GARCHLags',1,'ARCHLags',1,'Offset',NaN)
%%
% |Mdl| is a |garch| model object.  The software sets all parameters (the
% properties of the model object) to |NaN|, except |P|, |Q|, and
% |Distribution|.
%%
% Since |Mdl| contains |NaN| values, |Mdl| is only appropriate for estimation only.
% Pass |Mdl| and time-series data to |estimate|.  For a continuation of this example,
% see <docid:econ_ug.buofsf_-1>.
