Error in nonparametric survival analysis

[VitoAmoroso]

I cannot run nonparametric survival analysis with SAS OnDemand for Academics anymore.

It appears this error:

79

76

ERROR 79-322: Expecting a (.

ERROR 76-322: Syntax error, statement will be ignored.

Is there any solution?

Hard to tell since you did not share the full log for the step.

Thanks for your reply. This is the full log:

I noticed that the code 0 for censor is the problem. If I insert another value (i.e. 2) the analysis starts...

Here is proper log entry showing a similar error I generated. Best is to copy the text from the log for the entire procedure or data step, on the forum open a text box using the </> and paste the text. The result would look like:

100  data junk;
101     x = rand 'integer',5);
                 ---------
                 22
                 76
ERROR 22-322: Syntax error, expecting one of the following: (, [, {.

ERROR 76-322: Syntax error, statement will be ignored.

102  run;

The text box is important to preserve formatting as the forum software will reformat text so the indicators of where the error is detected, the underscore characters, will not appear where they should.

The fix is usually to enter a ( in the appropriate place:

103  data junk;
104     x = rand ('integer',5);
105  run;

NOTE: The data set WORK.JUNK has 1 observations and 1 variables.
NOTE: DATA statement used (Total process time):
      real time           0.01 seconds
      cpu time            0.00 seconds

I think the right syntax of proc lifetest is :

proc lifetest data=WORK.IMPORT;
time 'Overall survival (months)'n*Censura(0);
run;

Here 0 is a value of Cnesura which stands for the censored flag .

Error in nonparametric survival analysis

HI 

I am getting this error message - suddenly, I lost ability to input from task and utility non parametric survival (0) all other numbers work well. Any help would be appreciated (see error message below)

[Ksharp]

you need put 0 or 1 which is the value of Censor_OS after it :

proc lifetest data=HMAVEN.ALL;
time Overall_survival*Censor_OS(0);
run;

Hi 

you are right if you correct the code and put the in the code as here = time T*Status(0);
But if you try to put the 0 in the box where you have to put the censoring value , it wouldn't accept this but i accept any other values not 0 , any solution for this or i should cahnge the coding in the table to have 1 for censoring. This error is even if you tried to use the already uploaded BMT file in SASHELP
