expert needed...

Can somebody of you advanced guys come over to the Level I - thread and solve this two company - problem? Many thanks in advance…

i am laughing to myself that i’d ever even open up a thread entitled “expert needed”… our boys answered it well so no need for me to chime in. that question was vague- depending on if you’re asking from the perspective of Co A or B you get 2 diff answers. i miss level 1. really. a lot. back to dickey fuller and his big UNIT root problem that is.
