Here we go again. :-|

Check out the "Relative Importance of predictors in regression" thread

Happy December!

That part is straight forward enough but I have a main independent variable that ide like to control for in the examination of all of the other independent variables. My question is would I need to make this an "offset variable" in my models? I've been looking through the literature and there's no clear answer available.
