GARCH(1,1) without constant in variance regressor
Posted: Thu Aug 11, 2016 6:44 pm
I know that EViews can not drop the constant term in the variance equation.
Is there any reasons or the restrictions of the model such that the built in estimation method does not have this function?
Thanks for help.
