Hi all:

I have just run a Kaplan-Meier Survival Analysis. I want to compare the
survival rates for two groups (i.e., two different types of treatments).
SPSS, however, will not calculate the median survival time for these
groups. Each group has 15 cases. I am curious why SPSS did not calculate
this value? Thanks in advance.
