[R] Survival analysis with 60% random censoring

[zhongmiao wang]

Hello,
My study is to predict the likelihood an insurance policy holder will
not renew his policy in the coming expiration date.
My data has about 60% censoring and they are random, because customers
buy insurance at different time, however, the study has to be
terminated on a single date.  Any suggestion or reference is greatly
appreciated. Thanks in advance.

Best Regards
