I am working on a Cox PH model to predict policy life time (no control group
, just simple policy information).
Cox PH model is to predict hazard rate. How to get the baseline function
for Cox PH? I have searched for several days, but not find a good paper.
Appreciate it for your help !! | w**********n

hazard i think you need nonpara smoothing.Or use parametric estimation like
Weilbull. | f*******n

2. try to make the baseline parametric, besides Weilbull as mentioned above,
piecewise exponential would work too. You can find some tutorial about how
to use piecewise exponential in R for your problem. |
