Imagine I have hundreds sellers who have a set of customer ids and I count how many customers they share (the similarity of these sets). I need to look at the similarity between multiple sets and find a suitable method to calculate some coefficient to help me find the greatest similarity.
So I created pairs of sellers and calculated the Jaccard similarity coefficient for each pair.
The problem is if I want to extend this to triples, quadruples, and so on...
How can I compare the similarity between multiple sets?
