I do have two data-sets and I am not shure which version of the KM estimator to use. Both datasets contain the following columns:
ID | Issue Date | Last Recorded Date | Status
Wheras the Status can either be a) Default b) Current c) Fully Payed at the End
A Loan can run for Maximum 36 month such that Status c) only applies if all payments were made as sheduled.
- Set: Paymenthistory of Loans for which some are still current. This mean that I do have right cencored data and could therefore use S(t(i))= (1-d(1)/n(1))...(1-d(t(i)/n(t(i)) ?
- Set Paymenthistory of only terminated loans. This would imply that Status b) is never observed. Therefore - if I understood it correctly - I oberve the "whole" life of all loans and therefore have no censored data. In this case I use S(t)=# obs. life after t/N, where N denotes the number of observations.
So I am not shure whether I'm on the right track and whether my suggestions are right
