I have a products sales data in which there are two categories of products. First being the main product and second being the peripherals. Now I have to map the peripherals with the main product. How can i do that.
To start with I have one idea that peripherals will be always bought after the main product. And I have been advised to find solution on based on Mapping and Lag.
Kindly suggest any other thoughts or ideas. thanks in adv.
