Censored Data
Patient 100 was still alive when last observed on the 38
th
day after acceptance into the
program, so that his timesqr is known to exceed 6.164. The posterior distribution of
that patient’s timesqr shows that it is practically guaranteed to be between 6.164 and
70, and almost certain to be between, 6.164 and 50. The mean is 27.36, providing a
point estimate of timesqr if one is needed. Squaring 27.36 gives 748, an estimate of
Patient 100’s survival time in days.
