My data is insurance policy information, and the time window is Jan2010-
Jan2014. I need to build COX PH model to predict policy life time.
My question: the data is left censored and right censored. I did not find
any good discussion on left censored data. Also, some polices are incepted
after Jan2012 (late entry)
Any suggestion? how should i do with my data?
Thanks a lot |
