phreg assess

[deleted_user]

I am trying to use the assess statement in proc phreg to test for proportionality. When I use the example program provided by SAS, it works and show me the result fast. But when I work only own data, which is much larger than the example dataset, it took very long time (hours) to show me the result. Anybody know what is wrong with it?

check under "computational resources" in the PHREG documentation. You probably need more memory to get it to run faster.
