Hello, I ran the coxph model and everything worked fine. When I extract the output from the basehaz(y) function and was wondering if that baseline is cumulative or not. I then do:
F(t,t+1)=1-exp(h_0(t+1) exp(coeff(1)*covariate(1)+...)) Does this give me the probability of death from t to t+1 (in which case the baseline is not cumulative) or the probability of death before t+1 (in which case the baseline is cumulative) Thanks so much for your help!
