Kaplan-Meier Estimates
Note that in the above definition
•An
interval which ends in a censored observation with no observed
events has conditional probability of surviving within the interval
is 1.
•If
the largest observation time is censored, the KM (PLE) survivor
function never goes to zero
–We generally regard the KM (PLE) survivor function
to be undefined for times beyond the largest observation time in
this situation
