Re: % Contribution to Dependent Variable?

I'm a little weak in ANOVA right now as I haven't looked at in several years right now. Here's an example of what I hope to accomplish. For each week the independent variables are time spent with salesperson, TV commercial time, print advertising pages, while the dependent variable is automotive sales. I have information for this weekly for one year.

I want to boil it down to 4 numbers, a percentage contribution to auto sales of each of the 3 independent variables and a baseline % that is not attributed to the 3 independent variables.

I am not sure of which kind of ANOVA I should use and how to set up the experiment.

Thanks.
