I have built a model on log(units) sold and want to measure the contribution of each independent variable in the model (which are also in log) i.e. proportions of predicted units explained by independent variables.
So, basically I have a log-log model and want these contributions to be in actual units.
Under usual circumstances, I would be using an additive model but since now I am using a log-log transformation (multiplicative model) I think the process of calculating contribution will be different than additive. How should I go about it?
