I'm a Physicist but I'd like to know if there are some methods or models to predict the activity of the clients of a bank. I heard that banks are interested in this sort of analysis so I got curious about it. The thing is I don't know where to find information about this. Is there a name for such type of analysis? Can you recommend any good book to learn such methods?
EDIT (19/11/15)
In particular I'm interested in methods to predict the activity of the clients, say we know their banking movements and we want to know who of them will no longer be active the next month/year, for example.
