Something I've never gotten a good answer to: Say I have two groups of 1000 customers (e.g. US customers vs UK customers) and I want to compare the churn rates

Something I've never gotten a good answer to: Say I have two groups of 1000 customers (e.g. US customers vs UK customers) and I want to compare the churn rates between them. BUT these are users of varying ages, they didn't all sign up at the same month. It could be that one group is slightly younger or older than the other.
How do you compare churn rate of groups that aren't cohorted by age?
- dcl 6y agoYou can try the proportional hazard model https://en.wikipedia.org/wiki/Proportional_hazards_model https://en.wikipedia.org/wiki/Proportional_hazards_model In this setting, things like age, gender, or other features of interest are the covariates/predictors. You can then also use indicator features like UK or US for geography. If the geography based features are significant, then the difference in churn between the regions is perhaps not simply due to age etc.
