Customizing a PROC LIFETEST Failure Plot

daveconifer1 — Thu, 19 Dec 2019 00:26:35 GMT

I've used SAS macros %ProvideSurvivalMacros and %CompileSurvivalTemplates in the past to customize the plot that PROC LIFETEST generates. Now I'm generating a Failure plot with LIFETEST, and I found that these macros have no effect.

When I looked at the macro code I realized that this is because they are modifying the survival plot template.

Is there a corresponding macro(s) that I can use to modify a failure plot template?

Just for the record, here is my LIFETEST code.

ods rtf file="&ProjDir\QC\qc doc\tlfs\QC_&prog..rtf" nogtitle nogfootnote bodytitle;
 
ods graphics on;

ods select failureplot;
    
proc lifetest data = prep plots=survival (cb=hw failure test atrisk (maxlen=13));
     where newgroup = 1;
     strata newgroup;
     time AVAL*CNSR(1);
     run;
   
ods graphics off;
 
ods rtf close;

Thanks!

Right. They affect the survival plot and not the failure plot. I only provided macros for the survival plot, since that seemed to be the bigger need. At the time I did this, providing templates in *any* form beyond the proc template source form was controversial, so I was limited as to what I could do. It does seem that I wrote something somewhere about the failure plot. I will see if I can find it.

Hi Warren,

Thanks so much. I was actually looking at your instructions overnight for modifying a failure plot. I was just coming back here to mention that there are no SAS macros for the failure plot, only survival.

Thanks again. You've helped me in the past with the survival plot customization, as did all you well-written documentation!
