Chrun Model / Survival Time Analysis



Hi All,

I want to predict probability of customer churn given some set of characteristics. These characteristics can be time varying across customer life cycle.

Im trying to find - Given the customer is still active now, what is the probability of him churning in next 30 days?

I read about Survival Analysis, Hazard function gives me probability of a customer churn at that point given he has survived till that time. How do I estimate Hazard function, Cox PH gives me only the Hazard Ratio.

Any help would be highly appreciated.



For your problem when the window of target variable is certain and hence you need to only deal with uncensored data, I don’t think you even need a survival model.Here are a few things you need to keep in mind before using a survival model ( A simple logistic or CART model can do this job. But still if you wish to get kick started on survival analysis you can have a look at this article

Hope this helps,
