                 brand A    brand B

utilitarian goods Product 1 Product 2 Hedonic goods Product 3 Product 4 Can I use (product 1 NO. per transaction +product 2 NO. per transaction)/transaction total product NO. As IV called purchase ratio of utilitarian per transaction? And use (product 2 NO. per transaction + product 4 NO. per transaction)/transaction total product NO. In this way, product 2 purchase NO is the overlapped part of the two independent variables. Can I define it in this way? The correlation is -0.45
