Hi - Need help to do product affinity analysis for a Retailer. Products are categorized into categories such as say Baby Care, Male Hair Care, Female Hair Care etc. I can do affinity analysis at the product level using Apriori algorithm. I get the support, confidence and lift and using this I get the product affinity.

My objective is to tell that buying a product from say Category A means that there is chance that products from Category B also will be bought. However, I might not be able to apply same principle that I applied for individual products to Product Categories also. The reason is that in a customer's basket, there can be say 5 products of say Category A and just 1 product of category B, and in another transaction there might be 10 Category products and 4 Category B products and in another there might be 2 products of Categories A and B. There can be a similar imbalance across categories across transactions. In such a scenario, how do we perform affinity analysis.

Thanks in advance
