To include one more check option for including a trend (like for a > constant), The way the source code is now, that would be a little inconvenient, unless we're willing to add a "--trend" option to rhe "var" command. I wouldn't be against it, but adding a trend to a VAR is also very easy now, and such an option would be a tad gratuitous. Hence, I'm not either strongly pro nor against such a change. What do other list members think? > 2. To replace "Deterministic variables" with "Exogenous variables". Any adjective you use in this context is rather arbitrary. The word "exogenous" may mean at least 4 different things in the econometrics literature, so my very personal preference is for using it as sparingly as possible, unless the context makes what I mean very clear. But others may disagree.
