Hi all,
I have been struggling a great deal with this matter and as such I hope you could provide me with answer. I have added a dummy variable to my ARDL model to improve its stability (Eviews). However, if I estimate the CUSUM and CUSUMsq tests afterwards, they start from the point in time where the dummy variable turns 1. However, I am interested in reviewing the stability of the entire time period in scope of my analysis. Does anybody know how to enlarge the scope of the CUSUM and CUSUMsq tests? Curious to hear your thoughts. Many thanks!
