New to R studio and was wondering if there is a script or any suggestions to analyse the effectiveness of promotions in the CPG (Consumer Packaged Goods) industry? I usually run multiple regressions in excel but it has been difficult to get good models (rsq very low).
Any advise or link to similar examples would be appreciated.
