Timeline for Dependent variable is a function of independent variables; can I sensibly include them in a regression?

clarifications

| May 28, 2011 at 19:41 | comment | added | LCC | @probabilitylogic You're right, I have the impression that using OLS in this case just leads to trivial assertions. Probably it would be a better idea to either use other techniques like @Manoel suggested, or just proceed to more interesting questions like the one you proposed (which is casually similar to one of those we had in mind). | |

However, because you already know the factors which determine GPA - namely the grades in various courses, it may make more sense to model those factors rather than GPA. Perhaps a "better question" might be, for example: What factors are most strongly associated with high math scores?. | |
