This extension also includes recurrent events data and left-truncation of. 5910 F Chapter 71: The PHREG Procedure failure times. The theory of these models is based on the counting process pioneered byAndersen and Gill

The common statistics that you output from PROC LIFETEST are Median, 95% Confidence Intervals, 25th-75th percentiles, Minimum and Maximum, and p-values for Log-Rank and Wilcoxon. Additionally, you can use PROC PHREG to create Hazard Ratios and 95% Confidence Intervals.

Starting in SAS/STAT 14.3, you can use the EVENTCODE(COX)= option in the PHREG procedure to perform the cause-specific analysis of competing risks by fitting the cause-specific Cox models to different causes of failure 1.
