I have 21 groups (treatments) for which I do survival analysis as follows:
proc lifetest data=CPB ;
time Days*Status(0);
strata Strain / test=logrank adjust=sidak;
run;
Is there a simple way of generating CLD from long table with pairwise comparisons similar to option "pdiff lines" in GENMOD PROC?
Thanks,
Rosta
Hello,
Unfortunately, PROC LIFETEST cannot generate an item store.
Otherwise you could subsequently use PROC PLM with LINES option on LSMEANS Statement.

Thank you for the answer. If there is no such bult-in function in PROC LIFETEST, could anybody recommend any SAS script or even external tool to convert pairwise table to CLD table? I know it could be done manually but for long table it is not so easy (see example, complete table is about 5 times longer). Thank you.
