Let's say I have two stores, A and B, and let's say I have two products in the same department: product 1 and product 2. Let store B have product 2 which store A doesn't have, both stores have product 1. Is there a way to calculate how much cannibalization will take place on product 1 by implementing product 2?
Or, can I do a general approach and use a chi square on their department to see if store B has a higher performance in that department and then if that's the only difference in the products offered, and if they're similarly performing stores that introducing product 2 will increase that departments performance for store A?
If you have some scholarly articles that would be great as well!
