In the SAS/STAT User's Guide, the "code for this example" in PROC PHREG Example 16 Concordance and ROC Curves contains an incorrect data set. The first 24 observations for the Liver data set were omitted, and the program does not reproduce the documented results.

See the Full Code tab for the correct test program that reproduces the results shown in the documentation.
