in PROC PHREG, is it possible to obtain a "failure" plot instead of a survival plot?
for example, below will produce an adjusted survival curve.
proc phreg data=x plots(overlay)=s;
class trt;
model;
baseline covariates=x out=y SURVIVAL=Survival /diradj group=trt;
run;
what I'm interested in is a failure curve to show cumulative probability of failure
In PROC LIFETEST when can request to change the default survival to failure curve. Is this available in PHREG?
proc lifetest data=x plot=(survival ( failure));
..
run;
Thanks
Hi,
No, the probability plot of failure is not possible to obtain directly from phreg - not as far as I know.
But, it is not more difficult to obtain than to calculate 1-survivalprobability.
data y;
set y;
prob_of_failure=1-survival;
run;

Thanks for response. I couldn't get it to work using any of the proc options. However, I was able to manipulate the template for the survival plot (Stat.Phreg.Graphics.Survival), and specifying (y=eval(1-SURVIVAL) ) in the seriesplot statement.
