Question

Below is the survival data for 4 heart transplant patients, where T is the time to event (or censorship), X recorded the patient care score and C is the censorship variable, with C=0 as censored. Suppose we estimated a proportional hazard model using the Cox regression, and found the coefficient estimate to be -2. What's the partial likelihood at time T=5? Hint: you may need to sort the data before doing any calculation. Patient ID T C X 1 8 1 6 2 1 0 3 3 5 1 2 4 1 1 2 .2 .0003 .9997 .5
