The LIFETEST procedure in SAS/STAT is a non-parametric procedure for analyzing survival data. This procedure in SAS/STAT is specially designed to perform nonparametric or statistical analysis of interval-censored data. We can use ICPHREG procedure in SAS/STAT for interval censored data just like the ICLIFETEST procedure. We can use the TEST statement to test whether the underlying survival functions are the same between the groups.
