proc lifetest , weight

[Ivy]

The weight statement in proc lifetest  can not output weighted ods table of  CENSOREDSUMMARY.

Any clue?

Thanks!

ods exclude PRODUCTLIMITESTIMATES;
ODS OUTPUT QUARTILES = SURVQTLE  CENSOREDSUMMARY = SURVNUM;
ods graphics on;
PROC LIFETEST DATA=_adtte METHOD=KM ALPHA = 0.05 plots=survival(atrisk);
strata trtpn;
TIME aval1*CNSR(1);
weight ipw;
RUN;
ods graphics off;

From the documentation it appears that the CensoredSummary depends on Method used and your method is not one of them.

CensoredSummary

Number of event and censored observations

PROC LIFETEST METHOD=PL | B | FH

Thank you, ballardw.
PL = KM , we can get "CensoredSummary" , but the problem is the summary is not weighted.

Make a complete table ?

data new_adtte;
set _adtte;
do i=1 to ipw;
output;
end;

PROC LIFETEST DATA=new_adtte ...............

Hello,

Not sure if there's a "way around" here...

Documentation WEIGHT statement (LIFETEST procedure) says :

You can use the WEIGHT statement only for the Kaplan-Meier curves. Other methods of estimating the survival curves using weights are not available.

Documentation "CensoredSummary" ODS Table Name (LIFETEST procedure) says :

CensoredSummary

Number of event and censored observations

PROC

METHOD=BRESLOW | FH | PL

I am / was looking at SAS 94 M7 documentation.

Thank you very much.
SAS 9.4 dose not have that statement.
I am glad the newer version document this.
