How to perform a comparison of means test in a scenario where a user can have multiple conversions? In the case where a user can have at most 1 conversion, one can simply do a comparison of proportions test. However, in a case where a user may have multiple conversions, I am unsure how to model this variable? A Bernoulli assumption is no longer correct.
As an example of what I am looking for: Suppose we have two variants A and B. A is the control and B contains a new feature. I would like to see if variant B leads to more conversions (given the same number of users). As each user can have multiple conversions, I cannot simply do t-test using the proportions of A and B. How would you handle this situation?
