Hello,

I borrowed the following code from SAS Stat document: Example 49.5
Time-dependent repeated measurements.

----------------------------
proc phreg data=Tumor1;
      model (T1,T2)*Status(0)=Dose NPap;
      output out=Out1 resmart=mart dfbeta=db1-db2/order=data;
      id ID Time Dead;
   run;
-----------------------------

Could you please explain what the last line (id ID Time Dead;) does?
Will deleting the line generate different results?

Thanks,
Duckhye Yang
